From the project
FOGBOARD is one of my first hardware projects that I have worked on! Feel free to open source anything! I will be trying to make more advanced versions in the future!
FOGBoard is a 2-key, 1-encoder, and a Macropad with a screen that is based off of the SEEED XIAO RP2040. It's firmware is based off of the QMK Firmware & C Language.
It serves as a shortcut tool meant to be used for reimaging computers - Making it easier to perform tasks with the FOG Server.
- Dual Layer 3D Printed PLA Outer Casing - 2 Mechanical Keys - 0.91" OLED Screen - Rotary encoder for scrolling and entering - Custom PCB
