Cybdokeebs keyboard: common questions

What microcontroller does the Cybdokeebs keyboard use?

The Cybdokeebs keyboard is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the Cybdokeebs keyboard PCB?

The Cybdokeebs keyboard measures 294 × 114 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cybdokeebs keyboard?

167 components, from 21 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 Cybdokeebs keyboard design files?

From the Cybdo/CybdoKeebs 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 Cybdokeebs keyboard design in my own project?

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

Can I test firmware for the Cybdokeebs 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.
