Description

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!

This specific listing uses the internal on-board antenna of the ESP32, which works great in almost all situations. Not requiring an external antenna means, you can keep your Flipper inclidung the mounted dev board in your pocket while you're on the move.

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

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.

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 devboard and all guides fitting that board also apply to this kit.

Firmware

The backpack is delivered flashed with Marauder, for Wi-Fi pen testing, deauthing, packet capture etc. but you can install every software that is supported by the official wifi dev board, as it shares the same ESP32 and same wiring. This means you can also use this backpack as a Black Magic debugger probe for example, which the official board is shipped with.

You can also write your own software obviously. Your imagination is the limit!
