Custom keyboard: common questions

What microcontroller does the Custom keyboard use?

The Custom keyboard is built around the ATmega32U4-A, from the AVR/Arduino family.

How big is the Custom keyboard PCB?

The Custom keyboard measures 292 × 99.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom keyboard?

135 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Custom keyboard design files?

From the balkacer/custom-keyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

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

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

Can I test firmware for the Custom 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.
