SR01-Keyboard-PCB

Intent

A 1-key¹ "keyboard" development set, with QMK, ZMK and custom f/w.

Features

This is not a "keyboard" per-se, it's a PCB that allows you you, with a SeeedStudio XIAO RP2040 or XIAO nRF52840 module, to build:

• a 1-key MX-switch keyboard, with an RGB LED,
  - or -
• a 1-key HE (Hall Effect) switch keyboard, with a white LED,
  - or -
• a EC11 Rotary Encoder, with 4 RGB LED's,
  - or -
• a WHID solution, when paired with a SeeedStudio:
  • XIAO ESP32C3 module, or
  • XIAO ESP32S3 module, or
  • XIAO ESP32C6 module.

Why?

When I built the SR61, one of the MicroMod modules I wanted to build for was the SparkFun MicroMod ESP32 Processor.. and for that I bought a April Brother WHID Cactus ... and then never got around to it.

The intent was to create a Wireless KB (like a BT or 2.4GHz KB, but with WiFi), and also a whole bunch of additional features like a virtual web-KB, or the ability to configure the keys via it's own web interface.

This project is that idea, but modern. (The WHID Cactus is a ATmega 32u4 and ESP-12S combo. Old and limited.)

And then the tough was: Why not also make it a Adafruit NeoKey Trinkey- / DigiSpark ATtiny85 USB key- ... -like 1 key?

Under Development

I'll add more here after I've prototyped it - and built the firmware.
