ARC-Hardware: common questions

What microcontroller does the ARC-Hardware use?

The ARC-Hardware is built around the RP2040-ZERO, from the RP2040/RP2350 family.

How big is the ARC-Hardware PCB?

The ARC-Hardware measures 89.5 × 121.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ARC-Hardware?

145 components, from 39 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 ARC-Hardware design files?

From the IstratieStefan/ARC-Hardware 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 ARC-Hardware design in my own project?

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

Can I test firmware for the ARC-Hardware 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.
