Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

This four-key device, created by Mikey Sklar, is not really a macropad but a BLE keyboard: using Adafruit components, it is capable of outputtin any ASCII character.

A few months ago I put together a 4-key Morse code keyboard that translates out to ASCII characters and connects over BLE. It is a simple design with source code, BOM and design files – Mikey.

Based on CircuitPython and Crysknife's morsePico project, it uses Morse code dots and dashes with a lookup table to translate characters.



The key operations are the following:

  • Key 1: '.' # dot
  • Key 2: '-' # dash
  • Key 3: ' ' # will do a space between words or show the Morse code buffer contents
  • Key 4: SEND # translates Morse code sequence to ASCII, sends ASCII over BLE
