From the project
A mechanical keyboard
The articulation70 keyboard is a successor to the articulation80, with LEDs and a more personalised layout.
It features: - Variable pinky stagger, supporting ±1 mm vertically offsetted soldering configurations. - 3 × 6 main body, 3 thumb switches, 2 corner switches and 3 × 4 numpad layout. - Kailh Choc V1 hot-swap support. - A breakaway-able number pad. - Serial or I2C connection between halves. - Pro Micro-compatible controller support, however a micro-controller. with more pins are required to operate LEDs 2 and 3. - 3 LEDs - Reversible PCB to reduce manufacturing costs for hobby usage.
