Peripheral board v1a: common questions

What microcontroller does the Peripheral board v1a use?

The Peripheral board v1a is built around the RP2350A_C42411118, from the RP2040/RP2350 family.

How big is the Peripheral board v1a?

The Peripheral board v1a measures 100.2 × 100.1 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Peripheral board v1a?

171 components, from 60 distinct parts. The full bill of materials is listed on this page.

Where can I download the Peripheral board v1a design files?

From the BroncoSpace-Lab/scales-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Peripheral board v1a design in my own project?

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

Can I test firmware for the Peripheral board v1a 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.
