About the Equinox-V1 PCB
Equinox-V1 is an open source PCB design by ishantmahatopro, published on GitHub. It is a 2-layer board measuring 464.5 × 129.1 mm, with 246 components from 27 distinct parts.
Other key parts include the MCP23017_SO and USBLC6-2SC6. By type, the board carries 116 switches, 112 diodes, 8 resistors, 3 ICs, 3 capacitors and 2 connectors.
It belongs with the keyboards, iot & wireless and displays & leds designs in this gallery.
From the project
A 100% mechanic keyboard made from scratch
Equinox V1 is my custom full size (108 key) wireless mechanical keybaord, its built around a Adafruit Feather nRF52840 Express.
so basicaly i wanted a full size board that could go fully wireles over bluetooth but still work as a normal wired keyboard when i need it too, and i really didnt want to just buy some kit and screw it togther.. i wanted to actualy understand how the whole thing works like the matrix the diodes the I2C gpio expanders the battery the little screen ALL of it, so i designed the entire thing from scratch in kicad and fusion 360 which took forever lol
