Description

This is an addon board for the Flipper Zero multitool, providing Raspberry Pi Zero connectivity in a uniquely compact and covert formfactor.

It connects the Raspberry to the Flipper through UART, allowing them to talk to and complement each other. Usecases include the awesome pwnagotchi-flipper interface app by Matt-London as well as anything you can imagine running on your Raspi!

It also includes a PCF8523 real time clock module connected through I²C, provided you insert a CR927 cell onto the board (not included for shipping reasons).

Check out the Github repo for a full explanation, source files, build guide, as well as a collection of other designs in the same formfactor!

The board is designed to fit your Flipper wearing the silicon sleeve, but it also works without the sleeve.

The board comes fully assembled including a Raspberry Pi Zero 2W so you do not have to solder! It also comes in a 3D printed case made of black PETG

What makes it special?

While options exist to handwire a Raspberry Pi Zero W to your Flipper, the result is generally not "pocketable" and not robust to travel with. This kit allows you to connect your Pi in a compact and robust way that snugly fits your Flipper.

The entire project is designed with open source tools, allowing further modification and forking of the project. All source files are published in the Github repo using FreeCAD as well as KiCad.

Firmware

This board is intended to be used with something like the [Pwnagotchi](https://pwnagotchi.ai/), specifically the Pi Zero 2W compatible fork in combination with the Flippagotchi app to talk to your Flipper.

This software enables you to have the Pwnagotchi capture and diagnose wifi activity in the background, while rendering its display to the Flipper.

Since the Pi is connected to the Flipper through UART, you can run whatever code you want on the Pi that interfaces with your Flipper! For example you could write an app that offloads difficult computational tasks to the Pi.
