BlueMicro PyKey60

The PyKey60 is an open-source 60% ANSI mechanical keyboard PCB built around the Raspberry Pi RP2040 microcontroller. Designed by Pierre Constantineau under the BlueMicro brand, it targets CircuitPython beginners and custom keyboard enthusiasts who want a fully programmable keyboard without soldering switches. The board fits standard GH60-compatible cases, making it a drop-in upgrade for anyone building or modifying a compact mechanical keyboard.

Every key position features a Kailh hot-swap socket for tool-free Cherry MX-compatible switch installation, paired with an individual WS2812B NeoPixel RGB LED for per-key underglow lighting. The 14-column by 5-row switch matrix covers the full 60% ANSI layout with PCB-mount stabilizer support for the larger keys. An onboard piezo buzzer provides audio feedback for keystrokes and layer changes, adding a tactile-plus-audible dimension to the typing experience.

The RP2040 at the heart of the PyKey60 brings dual ARM Cortex-M0+ cores running at 133MHz, 264KB of SRAM, and native USB 1.1 support over a USB-C connector. External flash storage is provided by a Winbond W25Q128JVS 16MB NOR flash chip, giving ample room for firmware, keymaps, and CircuitPython libraries. The board runs KMK firmware — an open-source keyboard firmware written entirely in CircuitPython — enabling users to customize layouts, macros, layers, and RGB effects by simply editing Python files on a virtual USB drive.

All hardware design files including schematics, PCB layouts, and gerber files are published on GitHub under the CERN Open Hardware Licence Version 2 - Weakly Reciprocal (CERN-OHL-W-2.0), making the PyKey60 a fully open-source project from silicon to keycap.
