Keyboards: common questions

What microcontroller does the Keyboards use?

The Keyboards is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Keyboards PCB?

The Keyboards measures 297.2 × 105.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboards?

121 components, from 65 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keyboards design files?

From the kyleterry/keyboards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Keyboards design in my own project?

The repository has no license, so all rights stay with kyleterry. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Keyboards 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.
