What is it?

This is a 2.54mm protoboard for the Flipper Zero in a unique backpack-style formfactor!

Breaking out all GPIO of the Flipper it allows you to create your own designs for it, as well as adapting existing dev boards to this new formfactor.

The backpack style allows your design to neatly fit in your pocket on top of the Flipper.

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 repo also includes printable case options as well as a FreeCAD project for creating your own cases.

The kit consists of the 2 interlocking boards as well as the pin headers to connect them to your flipper. Soldering is obiously required to assemble the two boards at a right angle as seen in the build guide. Color of the connecting board up top may vary by stock. Usually black ones are supplied, matching the backpack itself, but white ones might be supplied when large enough orders come in too fast.

A basic 3D printed case can be optionally included.

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.

Why did you make it?

The Flipper Zero is an amazing tool to work with and develop for, and this board makes it easy to create permanent designs that fit nicely onto the Flipper.
