So you’ve got your Pi 3 with its built-in wireless LAN and Bluetooth, but what about your Pi Zero? Say hello to the IoT pHAT from Red Bear! This Zero-size board provides WiFi (802.11bgn / 2.4GHz) and Bluetooth (v4.1 / BTLE) connectivity direct from the GPIO header. You don’t need to use a dongle plugged into the Pi Zero’s solitary data micro-USB port via a USB OTG adapter. Just snap it on top of a Raspberry Pi Zero (or really, any Raspberry Pi with a 2×20 connector)!
The IoT pHAT provides a neat and convenient way to add WiFi and Bluetooth connectivity to your Pi Zero, while freeing up the USB data port. Using the same wireless radio chip as the Pi 3 results in reliable signal strength and quality via an on-board or optional external antenna.
As with other pHATs, it works with all of the 40-pin Raspberry Pi variants – 2/B+/A+/Zero – but using it with the Pi Zero makes for a super-tiny package.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
