Keyboard: common questions

What microcontroller does the Keyboard use?

The Keyboard is built around the ProMicro, from the AVR/Arduino family.

How big is the Keyboard PCB?

The Keyboard measures 109.2 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard?

23 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keyboard design files?

From the Haxerflaxer/PCB-Kailh repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Keyboard design in my own project?

Yes, under the terms of its GPL-3.0 license, which Haxerflaxer chose for the repository.

Can I test firmware for the Keyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
