Cybdokeebs macropad: common questions

What microcontroller does the Cybdokeebs macropad use?

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

How big is the Cybdokeebs macropad PCB?

The Cybdokeebs macropad measures 94 × 114 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cybdokeebs macropad?

77 components, from 14 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 macropad 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 macropad 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 macropad 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.
