Kustom keyboard: common questions

What microcontroller does the Kustom keyboard use?

The Kustom keyboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Kustom keyboard PCB?

The Kustom keyboard measures 277.2 × 107.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kustom keyboard?

164 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kustom keyboard design files?

From the jhynes94/kustom_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 Kustom keyboard design in my own project?

The repository has no license, so all rights stay with jhynes94. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kustom keyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
