Now available with an external antenna jack!

By request, this listing now includes the option for an external WiFi antenna capable board! This includes a case with an external antenna jack, the ESP32 with an antenna connector fitted, as well as the required antenna cable.

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 kit 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.

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

You have the option of choosing between a kit using the ESP32's internal antenna, or one featuring an external antenna jack. These boards differ by the part number of the ESP32 (-I vs non -I) as well as the supplied case. The case for the external antenna option features a female SMA jack as well as a male SMA antenna.

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 original board does not allow the use of an external antenna jack, wich this project optionally does. This is possible by using a different part number ESP32, that has a specific jumper set as well as a tiny antenna jack mounted on the board.

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.

Options

You can choose between boards using the internal antenna vs an external antenna jack. They differ by the ESP32 part number (The external antenna one has the antenna connector fitted to the chip as well as a small jumper set) and the supplied 3D printed case. (The external antenna one obviously includes an antenna connector)

All pictures done in the white studio are from the "internal" one, while the onces on the wooden table are from the "external" one.
