What is it?

This is an addon board for the Flipper Zero multitool, providing Wifi functionality in a uniquily compact and covert formfactor.

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 delivered flashed with the Black Magic Debugger firmware, just like the original board is during delivery. It was however designed with alternative firmwares like Marauder in mind.

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.

This kit does not feature an antenna jack to add an external Wifi antenna. (Since this is using an -I model of ESP32, which do not feature the antenna). With enough requests, a run with ESP32 models featuring the external antenna can be created as well.

What makes it special?

In contrast to the original Wifi dev board, it comes in a unique "backpack" formfactor, hugging the Flipper snugly, fitting neatly in your pocket during operation. It also has a Micro SD card slot to save captures or whatever else you can come up with.

An optional 3D printed case can be included to further protect your board and improve visual appearance.

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.

Other than that it behaves like the original FlipperZero wifi debugger module and all guides fitting that board also apply to this kit.
