About the Ghoost Board

Ghoost Board is an open source PCB design by Broccoliux, published on GitHub. It is a 2-layer board measuring 319 × 142.5 mm, with 359 components from 19 distinct parts.

Other key parts include the nice!nano, 74AHCT125, MCP73831 and ME6211-3.3V. By type, the board carries 90 capacitors, 84 switches, 84 LEDs, 84 diodes, 6 resistors and 4 ICs.

It belongs with the keyboards, iot & wireless and power & battery designs in this gallery.

From the project

A fully custom 100% mechanical keyboard with a custom black PCB, hot-swap clicky switches, and full RGB where every internal component is hand soldered and nothing is by assemble.

Broccoli Board is a custom 84-key 75% keyboard I designed completely from scratch. The PCB is designed in KiCad, the case in Fusion 360, and the firmware runs on ZMK. It's fully wireless over BLE 5.0 via the nice!nano V2, has per-key RGB LEDs reverse-mounted on the back of the PCB, and uses Kailh hot-swap sockets so I can swap switches without touching a soldering iron.
