PCBA: common questions

What microcontroller does the PCBA use?

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

How big is the PCBA PCB?

The PCBA measures 93.5 × 72.5 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the PCBA?

132 components, from 34 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 PCBA design files?

From the kalliod/PGKB 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 PCBA design in my own project?

Yes, under the terms of its GPL-3.0 license, which kalliod chose for the repository.

Can I test firmware for the PCBA 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.
