About
Mechatron is a 65% mechanical keyboard. It has some features listed below:
- An OLED Display [SSD1306]
- A Rotary Encoder [EC11]
- RGB Underglow
- Tactile Switches
Firmware
The firmware will be KMK which will be written in micropython, as I am using a Raspberry Pi Pico, it makes this easier. Still working on the firmware of the keyboard, for updates check the JOURNAL.md file!

Questions
How big is the Mechatron Schematic PCB?
It measures 397 × 147 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mechatron Schematic use?
172 parts, built around the WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mechatron Schematic KiCad files?
From the Swamstick911/keyboard repository on GitHub, at the commit this page was made from: the board is PCB/Mechatron Schematic.kicad_pcb and its schematic PCB/Mechatron Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mechatron Schematic design in my own project?
Its repository states no licence, so its author keeps all rights: ask Swamstick911 before reusing the design.
