ADCS board: common questions
What microcontroller does the ADCS board use?
The ADCS board is built around the RP2350_80QFN, from the RP2040/RP2350 family.
How big is the ADCS board?
The ADCS board measures 90.2 × 95.9 mm, has 4 copper layers and is 1.6012 mm thick.
How many components are on the ADCS board?
182 components, from 57 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 board design files?
From the pete4radio/SAMWISE-1-2-HW-Training 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 board design in my own project?
The repository has no license, so all rights stay with pete4radio. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ADCS 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.
