Know before you buy
This is a DIY kit that requires basic soldering skills to connect the components. You will also need to be comfortable compiling and flashing custom ZMK firmware for both the dongle and your keyboard.
While the included display module is technically a touch-capable screen, the Prospector does not utilize this functionality. The screen is intended for visual feedback and status monitoring only.
No, the 3D-printed case is not designed to support a proximity sensor. It is optimized for the included LCD module and the Seeed Studio XIAO nRF52840 core.
The brass threaded inserts significantly improve the durability of the assembly. They allow you to securely fasten and unfasten the case screws multiple times without stripping the plastic threads, making it much more robust than standard screw-into-plastic designs.
The Prospector is designed specifically for ZMK-based wireless keyboards. To function correctly, you must configure your keyboard's firmware to pair with the dongle as a central device.
You will need a soldering iron, solder, and a screwdriver compatible with the included hardware. Basic tools for firmware flashing, such as a computer with the ZMK build environment set up, are also required.
