Rp2040 8key: common questions

What microcontroller does the Rp2040 8key use?

The Rp2040 8key is built around the C2040, from the RP2040/RP2350 family.

How big is the Rp2040 8key PCB?

The Rp2040 8key measures 110 × 38.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp2040 8key?

52 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 Rp2040 8key design files?

From the kata0510/rp2040_8key 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 Rp2040 8key design in my own project?

Yes, under the terms of its MIT license, which kata0510 chose for the repository.

Can I test firmware for the Rp2040 8key 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.
