An open-source 60% QMK-compatible split ergo keyboard.

My next iteration of my personal split keyboard called the Cantaloupe – BucketInABucket.

The layout is based on the Ergodash layout with the inner-most keys removed and an improved thumb cluster. (The layout was only used as a reference, the board is a completely new design.)

Plenty of design cues have been taken from the YAEMK for version 2.0, especially with regards to the microprocessor section and the way that keyboard implements a fully reversible design.

Features

  • 30-key layout, pinky stagger, arrow keys.
  • On-board ARM (changed to STM32F4x1CxUx: F401 and F411 both compatible) processor
  • Kailh hot-swap
  • USB-C input and split connect ports with full ESD protection.
  • 0.96" OLED
  • Rotary encoder and Pimoroni trackball (replacing one encoder).
  • Reversible design which means lower PCB cost.
  • JTAG/SWD breakout header for an alternate means of programming the board.
