Raspberry Pi Pico W

Added to your shopping cart

The Raspberry Pi Pico W builds upon the great cost-for-performance metrics of the Pico and add WiFi to the board. The Pico W features the same attributes as the Raspberry Pi Pico and also incorporates an Infineon CYW43439 wireless chip. CYW43439 supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth® 5.2, supporting Bluetooth® Classic and Bluetooth® Low Energy (BLE) functionality - with the temporary exception of ACL/SCO — along with both the BLE Central and Peripheral roles. Things are also configurable so you can enable Bluetooth® Classic and BLE either individually, or have both of them available at the same time.

The Raspberry Pi Pico line is a low-cost, high-performance microcontroller board with flexible digital interfaces. It feature the RP2040 which marks Raspberry Pi's first microcontroller designed in-house. Pico provides minimal (yet flexible) external circuitry to support the RP2040 chip (Flash, crystal, power supplies and decoupling and USB connector). The majority of the RP2040 microcontroller pins are brought to the user IO pins on the left and right edge of the board. Four RP2040 IO are used for internal functions - driving an LED, on-board Switched Mode Power Supply (SMPS) power control and sensing the system voltages.

Pico uses an on-board buck-boost SMPS which is able to generate the required 3.3 volts (to power RP2040 and externalcircuitry) from a wide range of input voltages (~1.8 to 5.5V). This allows significant flexibility in powering the unit from various sources such as a single Lithium-Ion cell, or three AA cells in series. Battery chargers can also be very easily integrated with the Pico powerchain. Reprogramming the Pico's flash memory can be done using USB (simply drag and drop a file onto the Pico which appears as a mass storage device) or via the Serial Wire Debug (SWD) port. The SWD port can also be used to interactively debug coderunning on the RP2040

Pico has been designed to use either soldered 0.1" pin-headers (it is one 0.1" pitch wider than a standard 40-pin DIP package) or can be used as a surface mountable "module", as the user IO pins are also castellated. There are SMT pads underneath the USB connector and BOOTSEL button, which allow these signals to be accessed if used as a reflow-soldered SMT module.

Fun and lots of potential

I picked this up because why not at this price? I followed this tutorial https://projects.raspberrypi.org/en/projects/get-started-pico-w and had it working in under 10 minutes. The ability to have wi-fi on a microcontroller like this in the Raspberry Pi family is too great to pass up. Now to find a proper project for it!

It works as expected!

This thing is fast! I've moved over from other microelectronics that have rather limited memory and cpu power compared to this. It's a breath of fresh air to have a little more breathing room when writing code.

Jeez Louise!


Amazingly good

I am thrilled with this unit. More powerful than I ever imagined an embedded system to be with all the wireless connections I crave (soon). Programming is easy. I've been using ESP32 for my systems but this is a better solution with more capability. Lots of I/O, most of the standard interfaces. Looking forward to using the clock more after some experimentation.

Only drawbacks are the amount of flash (which I expect to change) and missing I2S.

It seems impossible that this is so inexpensive....

Works Ok

Haven't finished testing it but it appears to perform pretty well.

just what I was looking for

Micropython speeds up development. Hopefully there will be better availability soon.


Product is great, shipping was incredibly slow

The brain behind the Pizza Press

I am replacing the Raspberry pi pico with the pico W on my automated Pizza Press. Working towards a web app that lets one watch the pizza dough being pressed into a perfect 12" pie to the desired thickness on a web app. The pico controls the press motor and reads the load gauges and controls the platen temperature by the temperature of the dough this and the web cam is sent to the web app. One can adjust the pressure to get the correct thickness of the dough for a perfect pizza every time.

Wi-Fi enabled micro controller

Works great. If you are used to circuit python it will run circuit python. I decided to try out micro python and It seems easier to use with git. Currently it doesn’t populate as flash storage but there is a python utility for copying files to the pico w. It connected to the WI-FI on the first try.

Nice microcontroller

So far so good. Nice and small; low power; easy to figure out and program.

A fun little toy I guess.

I haven't really understood why the RP2040 has been getting so much attention, because realistically what does it do that any other ARM microcontroller doesn't?

With the addition of Wi-Fi, it becomes something a little more interesting, but it's really a breadboard toy, it's not really easy to build into a project, plus the relative lack of flash or RAM makes it difficult to do network-based loads.

I also would like a hardware reset switch.

Check my delivery status. Plz.

It's been a month since I placed the order and I still haven't received it. Delivery seems to have stopped during on the way, but FedEx doesn't tell me the reason. What should I do?

This is the best Raspberry pi I have owned. A must buy for your build kit.

A unique board for a unique project...

I've been waiting a while for the PicoW to become available again. Sometimes you need just a little CPU and WIFI that's capable of very low power intermittent operation. The W falls nicely into this niche at a good price point. Since it uses standard libraries and tools it is a breeze to "What If" prototype something and get a sense for the fit. I can think of dozens of uses where it is just enough more capability than the trusty go to the ESP8266.

Raspberry pi pico w

Both chips worked perfectly out of the box. Devices will be evaluated for bioelectrical/nonmedical application. Thanks for your continued support and timely service.

Great little IoT device for Maker experimenting

These are great little IoT devices for Maker experimenting. Good for learning micropython, web server tinkering, sensor/IoT type projects. Convenient to use. Pretty good docs and project examples online.

Glad to have this while we wait for full Raspberry Pi's to come back.

Still setting in that this product is real

MicroPython support and the ease of programming over USB makes using a pleasure

My soldering skills aren’t what they used to be so next time I may go with pre-soldered headers.

My new macro pad powered by a pico w!

I built a macro pad with cherry mx switches. I 3d printed the base and key caps and wired them all to the pico inside it. Works great!

Really like the Pico W!

Adding WiFi connectivity to the Pico board is a great addition to an already very capable board. With its dual Cortex-M0 cores I can have my application running on one core while handling the network activity with the other.

Works great and easy to program

The first thing I did was upload the MicroPython firmware. With the Pico, I wrote everything in C, but with the Pico W, I decided to use Python. Very easy to make a web server to control a couple of relays for my project. I used Thonny at first, but then it decided to "upgrade" the MicroPython to the standard Pico version, and couldn't get over it, so I switched to PyCharm. Great board. Great price. I'll be using them a lot.

Pico W is fantastic I'm gonna buy a few more...

Shipping was excellent 👍 product was packaged great 👍 what I love most is how easy it is to read the gpio pinout map I'm looking forward to making a pi drone and adding extra parts to my home security...
