keyboard's Introduction

A 36-key keyboard

About two years ago I switched to a 36-key keyboard and I have not looked back since. So I thought, why not make my ideal keyboard hardware and software?

Hardware:

  • 2x 18 keys
  • 2x rotary encoders
  • 2x OLED screens (256x64)
  • 2x Raspberry Pi Pico

Software:

  • low latency

  • different applications (handled by the second core)

    • pin protection
    • LLM client (via API, future on-device?)
    • todo tasks
    • timer for focus
    • settings
    • snake

    Communication

The two halves communicate over UART. Power, GND, and UART are connected over a USB-C cable. I am not using the USB protocol for this. I am splitting the USB lines on both ends and only connecting power, GND, UART RX, and UART TX.

The primary half communicates with a PC over USB (TinyUSB).
