Raspberry Pi Zero W

Added to your shopping cart

The credit-card-sized computer has become even smaller! The Raspberry Pi Zero W is still the Pi you know and love, but at a largely reduced size of only 65mm long by 30mm wide and at a very economical price. With the addition of wireless LAN and Bluetooth, the Raspberry Pi Zero W is ideal for making embedded Internet of Things (IoT) projects. The Pi Zero W has been designed to be as flexible and compact as possible with mini connectors and an unpopulated 40-pin GPIO, allowing you to use only what your project requires.

At the heart of the Raspberry Pi Zero W is a 1GHz BCM2835 single-core processor with 512MB RAM. Quite frankly, this Pi is about four times faster that the original Raspberry Pi and is only a fraction of the cost of the current RPi3.

The setup for the Raspberry Pi Zero W is a little more complicated than on other Pis. Because of the small size, many of the connectors on the Pi Zero are not standard. For starters you will want a Mini HDMI to HDMI cable or adapter to connect to your monitor. You will also need a USB OTG cable to connect a USB device, as well as a unique CSI camera cable. No matter how you want to use your Raspberry Pi Zero W, you will need a microSD card with an operating system and a high-quality 5V power supply to power your board.

Important: The Raspberry Pi Zero W is limited to one unit per customer account.

  • GiladKap / about 7 years ago / 2

    I want 10. When will the limit be removed?

    • There are no plans to remove the limit. The limit has been put in place by the Pi Foundation and carries over to all of their distributors (including us). Sorry for any inconvenience this causes.

      We do sell our Basic Kit which does not have a limit and includes all the cables you need to get started (since the board requires less common ones).

      • kewakl / about 7 years ago / 3

        Answers my question... I do not want to buy under this requirement. Im not going to buy all the extra baggage for a $10 board. Pi foundation need to pull out the proverbial head from the proverbial hole and JUST MAKE MORE of the zero/zeroW. Stop playing this game. It IS NOT like it cannot be done.

  • BlueOval / about 4 years ago / 1

    These things are never in stock when I look. I have a great use idea for it but I guess with the 1 unit limit and high demand/low supply I will go ahead and forget that...

    • santaimpersonator / about 4 years ago / 1

      There is no limit if you buy any of the kits. The quantity limit is discussed in the comment above. Unfortunately, it isn't something in our control.

  • tetsujin / about 7 years ago / 1

    A word of warning about the "1 per customer" limit: If you have ordered the item in the past, and attempt to order another one, it will cause a delay in shipment of your order, and ultimately the Zero will not be part of the shipment. (In other words, yes, they really mean it.)

    (In my case, I thought "1 per customer" meant "1 per customer per order" - I guess because I don't know what words mean. Anyway I ordered and almost immediately my order went into "exception" status. It didn't indicate what the exception was, and not wanting further delays I contacted Sparkfun via chat to resolve the issue.)

    I think it's worth pointing out that the order system has all the information it needs to pre-emptively block such an order at checkout time: the system clearly knows I've ordered a Pi Zero W from Sparkfun in the past ("You last ordered this item on ....") but it doesn't prevent you from ordering another one. You just won't get it, and it'll delay other stuff you ordered.

RPi Zero Nixie Tube Clock

My RPi Zero became the heart of a Nixie tube clock with hours, minutes and seconds digits. What made this particularly a good fit was the low cost of the Zero coupled with the ability to connect to WiFi. Now when powered-up, or when a power glitch occurs, the Pi reboots, connects to the WiFi network in our home, and sets the time correctly, all without human intervention (I don't know why there are not WiFi connected clocks on the market!). It was nice to use the Zero's VNC capability for the hardware checkout and software development. Python3 was used to read the system clock, format the data into three bytes and shift that out the SPI interface. Hardly any code at all. Besides the Zero the clock used three CD74HC595 shift register/latches connected to the SPI port, six K155ID1 (SN74141) binary to decimal decoders and a purchased high voltage supply PCB (170V) to light the Nixie tubes. I still need to build a case to enclose the clock which has a tinted Lexan window, a board holding the Nixie tubes, an electronics board, then a back panel, all separated on quarter inch spacers. I can send pictures if you want...

Does what it says on the tin

It's a Pi Zero W. Not the fastest or newest Pi, but that's not what we're after with this board. It's small, runs Raspian, and with a little care, you can get ROS and Arduino running on this little baby too.

You know the name. You know the capabilities. Good Luck, and Enjoy!

My only complaint is availability

It's really annoying to have to buy these one at a time.

Otherwise, it's an absolutely awesome product at a fantastic price.

It just works

I've used Pi-w's in several projects now from audio playback device to autonomous robot with a camera and they just work out of the box. The addition of wifi was something that put the icing on the project cake. At 10 bucks and roughly P4 performance you cant go wrong. No wonder they can't keep them on the shelves.

The best Raspberry Pi Zero so-far !

The Raspberry Pi Zero W has almost everything you could want in a tiny package and cost close-to nothing - What is not to like !

Perfect for my application

Attached an SDR and using it to provide remote weather data to my home control system. Couldn't have been easier or less expensive!

Best features in this pricerange

for automation projects that have power but not data run to them, this device is hard to beat. I paired this with a 10W LED (and driver) to make a mulitcast alarm indicator for my ZoneMinder monitored ethernet cameras. Now I know when someone approaches my front door and I can move the indicator where ever I want (or build more) as needed. That assumes availabiilty of this part though. At this price, there will always be high demands for such a device. Just need to get them PXI booting!

A Full Blown Linux System for Experimental Bliss

Love it! RPi Foundation just has to keep up with demand!

I'm using it to drive SK6812 RGB LEDs with adafruit's neopixel python library. Great fun!


Small Yet Powerful!

Powerful processor yet Power Efficient. Running great as a small headless server, with Arch Linux. Can be used in a conductive enclosure, via an unpopulated UFL connector. As far as I know the serial port is used for the Bluetooth connection and so my project can't utilize the hardware UART without disabling Bluetooth, but for my current project is a non issue. WiFi connection is pretty good ~22Mbps down and 11Mbps upload, though the antenna has quite a few lobes and a few nulls; this isn't a problem though when connecting an external whip antenna via populating the UFL connector.

Best deal in small micro boards

This is my first raspberry PI project, not that I haven't wanted to try one out. The only problem was that I couldn't justify the $30.00us plus cost of a original PI for a simple project. The Raspberry PI zero W changed all that. For just $10.00us I could have it all in a small package. I could not say no. I choose a 3D printed robot with a cheap camera as my introduction to the PI, and I must say that it was so easy to use that I was kind of disappointed in a way. I wanted to tell everyone that I spent nights recompiling code and re-flashing chips, wiring interface boards etc, but as it turned out I just plugged in the camera, copied the OS and code onto the SD card plugged it in and turned it on.
It all just started working and working well, and my wife showed a few seconds of interest that I am confident wasn't faked. Once I have completed this robot I will definitely be buying another PI zero W.

No wifi

Sorry but this product does not work with internal wifi, we have to put a dongle.

It sounds like you may have a defective unit. Please contact our tech support team at techsupport@sparkfun.com for help.

Product is fine

Things are fine other in the fact that it took 2 weeks for FEDEX to get it to Wi. I gave up and ordered a zero from Newark in SC and it got to me in 3 days by usps. I also ordered some items from AllElectronics in CA and I had it in 3 days by usps. I don't use SparkFun any more on my bom(s) to my customers.

SparkFun is Awesome :)

It's great to be able to have a source for these at a substantially reduced price (vs Amazon's price of 25$), since I'm building a more than a few personal IoT projects based on them.

This is an excellent way to get started experimenting with IoT and your own ideas -- Think Small, Dream BIG :)

You can do a lot with this tiny single-board computer

I am enjoying all the different projects that you can do with this Single-Board computer. There are several other projects that I am working on how and I ordered this just a few days before the Raspberry Pi Zero WH came out. If you are planning to do projects with this board I would recommend getting the WH version. Other than that, this is exactly as advertised and shipped in a very sturdy box. Thank you SparkFun for making this experience a very good one :-)

works as intended. Kudos to SF for sticking with the official price.

excellent trade off between low power usage (~150mA) and capabilities (still running a full Linux system + WiFi). I used with a camera module as part of a smart home monitoring system with another RPi 3B as the server (MotionEyeOS + MotionEye). Can't beat the cost compared to commercial CCTV solutions.

Great board to tinker with, received with a little damage but works fine

It's nice to be able to get the zero w at list price here. I have an assortment of project ideas for these now so I will be buying more in the future.

The one I received from sparkfun is slightly damaged but seems to function fine, at least for my purposes. The black component labeled 4R7 adjacent to the camera connector is chipped. I'm not sure what that part is or if the damage prevents any functionality from working but I figure it's worth reporting that the product is being shipped in this kind of condition for those who care.

It's pretty common for there to be small chips in that part. (It's an inductor) If you have any trouble with it, let us know though.


I am really impressed that the zero's size is much smaller than I thought. Haven't started tinkering with it yet. But can't stop thinking of what to use it for.

Great Little board!

Great price, easy start-up, practically plug and play. A well-supported, all-inclusive single-board wi-fi enabled computer for $10 that can fit in your shirt pocket! What's not to like?

A low-end RPi board

The least impressive function of this board is the WiFi performance. With my experiences with the 3B, 3B+ and latest 3A, it is about 10dB lower than other RPi I have when measured at the same location. When I used it with a PCM5122 DAC hat to play the lossless compressed music was paused many times during the play back of the 10 files from a CD collection.

Best Pi so far

These are the best raspberry pi produced to date. Nowhere else can you get this powerful (and well supported) computer with WiFi, Bluetooth and high res HDMI video! Please continue to carry them!

Works fantastic as a airplay destination

I found a great cheap, extendable sound controller for the different rooms in my house. This PI + a cheap ebay PCM2704 sound card + sd card + this guys project https://github.com/mikebrady/shairport-sync turns this device into something I can reliably use as an airplay destination. It took a few hours to set the first one up.

Best OctoPrint system ever

I recently bought a PZW to run OctoPrint on my new Prusa MK3S 3D printer. The system plugs directly into the 3D printer controller and provides wireless control and access. It worked well enough that I will replace my Pi3B+ running my Lulzbot 3D printer with a PZW later this month. Controlling my 3D printer from my phone is awesome

Okay, but the purchase limit ruins it

It's a single-core RaspPi. It's not fast by desktop standards, but it runs circles around the computers I grew up with.

The big deal should be the price. At $10 apiece, they should be nearly disposable. When I first heard about this product, I had fantasies of 360° photo scanners; smart weather balloon payloads; player terminals at a gaming table; pen testing tools; costumes and props and gimmicks.

But the one-per-customer limit means this computer is my most irreplaceable computer. The cheapest one, the most disposable, the least capable... is the one I dare not use in a project because I can't get another.

If you're in a developing nation and this machine is the only one you can afford, go for it. But a model 3 or 4 is a much, much more capable as a personal computer and development environment. And since you can only get one of these things, what else are you going to do with it?

Great Device For Security Camera

Using it for a door bell type camera meant to be left on continuously. Used Noobs lite image and so far no crashes, bugs, etc. after being up for a week. Easy to set up as headless, didn't need any special cables or even a monitor. That's what I was looking for.

Its really small

Ideal board for remote camera systems. Noticeably slower than a Pi3. Cheaper than adding wifi to a Pi1 and you get bluetooth. In high demand so most places will only sell you one. Mini camera cable adds to the cost and you might need a usb otg cable too. No display port.

pi zero w

Just about everything you need to make a web controlled thingy. In my case this acts as a web controlled garage door opener and gate actuator.

Used python and flask

Love form factor, price. Performance suffers.

It’s a tiny, for real Pi! For now though, it’ll probably go in a drawer, waiting for a new project. It’s intended use (to drive a graphical TV display board) was too resource intensive. That’s not unexpected, and not the fault of the Pi. I wanted to try the small form factor.

If you have a physically small project that needs wifi and a relatively small amount of horsepower - less than a 3B/4 but more than Arudino/ESP32, or you want to run a pi on a battery, it’s worth trying for sure.

Not good for Node Red usage

I purchased to run node red applications. It appears that this raspberry pi does not support node red when you install from the Raspbian repository. Web search leads me to believe that the problem is that the processor in the zero is an ArmV6. It looks like it should work if you install JavaScript libraries that are compatible with the ArmV6. However, I don’t want to take this path because it appears to be to complicate the update process. I will use a pi2 instead.

Great mini computer

When you need more computing flexibility than you can get from a microcontroller but you need to save space and money.

Perfect for ADS-B

Needed a small Pi with built-in WiFi for my ADS-B project that would fit inside of any enclosure outside with SDR dongle. This worked perfectly.

No regrets and works great

Nice little board to setup a simple web server for my Picobrew Pro to work again, loaded software on a microSD card and worked right out of the box. Raspberry Pi's are easy for newbies! Built-in WiFi was the feature that I needed.


All works fantastic.. best product ever to mount my own server!!!

Never got it.

Still awaiting a response a reshipment from support. Been nearly a month since i ordered it.

Not sure what happened there, but a replacement is on the way!

Embeddable Single-Board Computer

The Pi Zero W isn't as powerful as the Pi 3 or 4 or Compute Modules, but it's easy to embed in tight spaces and cheaper when you just need a subset of features.

I've embedded Pis in:

-a mint tin to make a MintyPi handheld game emulator

-a desktop transistor radio--added an audio pHAT to make a radio which plays internet radio streams, digital audio files, and AM/FM broadcast radio

-HQ USB cameras which use the Pi HQ camera and stream the video over USB for a high quality webcam that's cheaper than many store-bought ones

-a case with audio pHAT to play music in my garage shop and basement stereos

Great product with weak documentation

The features and implementation quality are top flight. Raspberry Pi’s documentation leaves much to be desired!

Not sure how I could give this anything but a 5/5

It's the Pi Zero W! You probably know what it is and how amazing and capable it is for the price. There's endless documentation, projects and accessories for it. The only drawback is that it's hard to get your hands on many of these.

Be aware of what you want it for

It's a technical detail, but an important one. This is a 32-bit processor. It's 2021, and most of the software you'll find is 64-bit. This was the perfect solution for the low power monitoring application I bought it for, except that it wouldn't run version 2.0 of InfluxDb.

That's not a "fault" of the Pi Zero, just a point I wasn't aware of.

Great For What I needed It For

The Pi Zero is a perfect size for what I needed to have done, but I didn't realize the CPU was a single-core (but that makes sense to help curb the power requirements and heat dissipation. One thing I wished Raspberry had done was to keep the ports the same across all Pi's - instead of using a mini-HDMI why couldn't they have gone with the micro-HDMI like the Pi-4. Same thing with the micro-USB instead of going with the USB Type C for the power input. But other than my complaint on the ports the Pi Zero W is a very good deal.

Great little wi-fi audio device

I'm running Volumio and outputting over I2S to an external DAC. It booted flawlessly and performs very well. What's not to like for $10!!

Everybody loves Pi!!

I saw these were available and just bought 4x of them... not a single project in mind. Now? Well now they're an interconnected network of security tools and suites that do everything from alerting, to network sniffing, to IP/domain reputation analysis, etc - all feeding my on-prem (read: at my house) datalake.

Oh, and Sparkfun is cool too, I guess. Thanks!

Great little board

Small but very useful for a range of applications, from portable retro gaming to a functional (albeit a little slow) network attached storage, this board is sure to keep any hobbyist occupied. Great for hobby projects or as a learning tool for those interested in IT.

A remarkable bit of technology

Tiny, cheap, does everything - if you're not sure what your next project needs, just pick this one. For boot and forget applications, I prefer the Pico W which has a simpler development platform. But then this one allows full interactive debugging with VS Code if you want to set it up - pretty nice. The Pi community is an amazing resource for these products.

No reply from customer service

I filled out the form for customer service, saying that one of the (10) Pi's I got was not functioning. I have not received a response.

It can take a few days depending on backlogs; fill it out again if you haven't heard back in a week or so www.sparkfun.com/returns

Also be sure to check your email's spam folder(s)

Pretty good

Using class 10 SD cards, the I/O performance is a lot slower than even rotational drives. Doing an apt get/upgrade takes a while. I have 4 of these all with different class 10 cards and the results are all the same.

With that ONLY negative out of the way, I'd say these are otherwise amazingly useful. Gone are the days of low-level programming over a USB port. Today, we have a full Linux machine complete with pre-installed software like gpio, raspistill and raspivid for working with I/O and cameras. This greatly reduces the time it takes to develop with these devices. Throw in on-board wifi (I get about 1.3Mb/s average on mine) and there isn't much more to ask for. Bravo!
