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.
Features
- four keys, MX, hotswap
- NeoKey 1x4 QT I2C
- Adafruit LED Glasses Driver (nRF52840)
- Built-in USB-C charger
- 420mAh battery
- Wireless BLE v5.x
- Per-key NeoPixel LED
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
