Title: Cantaloupe V2.0 ergo split keyboard
Post by: Ariamella on Thu, 20 January 2022, 22:15:34

My next iteration of my personal split keyboard called the Cantaloupe. Key features include:

• Ergonomic 30-key layout including pinky stagger and arrow keys.
• On-board ARM STM32F4x1CxUx processor.
• MX switches with kailh hot-swap sockets.
• USB-C input and split connect ports with full ESD protection.
• 100% reversible design which means only a single board is needed for both sides.
• 0.96" 128x64 SSD1306 OLED support.
• Two rotary encoders supported above the thumb cluster, one on each side.
• Support for the Pimoroni trackball module is also available, replacing one rotary encoder slot.
• JTAG/SWD breakout header for an alternate means of programming the board.

Design cues have been taken from the YAEMK for this version, including the in-build jumper pads in the OLED and Trackball footprints, the JTAG/SWD header and the ESD protection.

The SSD1306 OLED modules I have looked at have pull up resistors already on the module. You do not need external pull up resistors.
