Hardware: common questions

What microcontroller does the Hardware use?

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

How big is the Hardware PCB?

The Hardware measures 370 × 155 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hardware?

157 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hardware design files?

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

Can I use the Hardware design in my own project?

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

Can I test firmware for the 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.
