Keeby20: common questions

What microcontroller does the Keeby20 use?

The Keeby20 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Keeby20 PCB?

The Keeby20 measures 81 × 116.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keeby20?

75 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keeby20 design files?

From the minhazislamnafi/KEEBY60-20 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Keeby20 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which minhazislamnafi chose for the repository.

Can I test firmware for the Keeby20 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.
