What is it?

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 project is supplied as a kit and requires beginner soldering skills to assemble the boards. All SMD components come presoldered. Check out the build guide.

All kits are delivered with a 3D printed case using black PETG.

This kit only includes the connecting boards, pin headers and all screws required. It does NOT include the Raspberry Pi Zero W.

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.

Parts delivered:

• Raspbery Pi Zero W carrier PCB
• Backpack connector PCB
• Pin headers
• Screws and Nuts to connect Raspberry Pi to carrier PCB
• 3D printed case
• Screws to connect the board stack into the case

Raspberry Pi Zero W NOT included!

Since batteries can't be shipped from here, a CR927 cell is required if you want to use the RealTimeclock.
