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 now with headers! 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 a populated 40-pin GPIO.
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.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

This is one amazing little device for the price and even for the specs!! I migrated my solar water controller from arduino over to this. I have built in all sorts of new features like data logging, web access to temps, logging to remote server etc. All of this can be done w Arduino, but having everything on one beard (wifi, bluetooth, SD) makes things MUCH easier and simpler
The pi zero works perfectly for my particular non-CPU intensive application. It is being used with a MMDVM modem for a digital radio node. Specifically DMR. I find the normal raspberry pi to be much faster at boot up however these little pi zeros are cute and draw almost no power. Mine is used in a mobile environment. So yeah! I'm ordering more.
It is working perfectly near as I can tell. I put a HAT on it. Stuck a memory card in it. and just like that the system was on line and running porting Digital audio both ways.
I have several Pi-Zero-W's some with hats some without doing much the same job.
Worked out perfectly, used it to replace a defective Pi Zero W board from a Zumspot kit. Ordered a second one on to build a ham shack world clock....
I like the range and amount of product information that Sparkfun provides. Always accurate and to the point.
The Pi Zero W has comparable power requirements to an Arduino with attached wifi shield. For applications requiring ADC the Pi Zero can be attached to the I2C ADS1015 sensor. Many other I2C sensors are also available. Plus, with a Pi Zero, I can code in interpreted languages like Python, and setup a web based (http) user interface, as well as store substantial data in an rrdtool database stored in the SD card.
My most recent Pi Zero project involves using a Pi Zero with an INA260 power sensor to monitor power consumption at a remote amateur radio installation. The power sensor monitors power consumption of an amateur radio mesh network node (www.arednmesh.org). The Pi Zero runs an Apache web server which allows any computer on the mesh network to view a web page showing the power being consumed by the node.

Sure it's not as zippy as the new 4B. But what is? This is a great size for embedded projects. IoT, Model Rocketry, RC Aircraft, Robotics. Great price too!
Had this in my hands within 2 days, connected via Putty and running a small DC motor using a motor hat within minutes. I did have an SD card with a working image already setup. Highly recommend Sparkfun and of course Raspberry, but they're almost impossible to get these days.
