Rp2040-minimal board: common questions

What microcontroller does the Rp2040-minimal board use?

The Rp2040-minimal board is built around the RP2040, from the RP2040/RP2350 family.

How big is the Rp2040-minimal board?

The Rp2040-minimal board measures 42.8 × 51.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Rp2040-minimal board?

31 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rp2040-minimal board design files?

From the Onaensar/rp2040-minimal-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rp2040-minimal board design in my own project?

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

Can I test firmware for the Rp2040-minimal board 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.
