Redox keyboard: common questions

What microcontroller does the Redox keyboard use?

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

How big is the Redox keyboard PCB?

The Redox keyboard measures 162.2 × 126.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Redox keyboard?

77 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Redox keyboard design files?

From the mattdibi/redox-keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Redox keyboard design in my own project?

Yes, under the terms of its MIT license, which mattdibi chose for the repository.

Can I test firmware for the Redox 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.
