Safety board: common questions

What microcontroller does the Safety board use?

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

How big is the Safety board?

The Safety board measures 186.6 × 107.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Safety board?

76 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Safety board design files?

From the UCLA-Bruin-Supermileage/SMV_boards_2024-2025 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Safety board design in my own project?

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

Can I test firmware for the Safety board 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.
