Keyboard61: common questions

What microcontroller does the Keyboard61 use?

The Keyboard61 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Keyboard61 PCB?

The Keyboard61 measures 288.1 × 97.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard61?

151 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Keyboard61 design files?

From the cho0h5/keyboard61 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Keyboard61 design in my own project?

The repository has no license, so all rights stay with cho0h5. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Keyboard61 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.
