ADCS: common questions

What microcontroller does the ADCS use?

The ADCS is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the ADCS PCB?

The ADCS measures 90.2 × 95.9 mm, has 4 copper layers and is 1.6012 mm thick.

How many components are on the ADCS?

187 components, from 58 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 ADCS design files?

From the stanford-ssi/samwise-avionics 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 ADCS design in my own project?

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

Can I test firmware for the ADCS 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.
