ArxRP2040: common questions

What microcontroller does the ArxRP2040 use?

The ArxRP2040 is built around the RP2040, from the RP2040/RP2350 family.

How big is the ArxRP2040 PCB?

The ArxRP2040 measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ArxRP2040?

31 components, from 16 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 ArxRP2040 design files?

From the ArxDraco007/ArxRP2040 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 ArxRP2040 design in my own project?

The repository has no license, so all rights stay with ArxDraco007. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ArxRP2040 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.
