Avionics-Mainboard: common questions
What microcontroller does the Avionics-Mainboard use?
The Avionics-Mainboard is built around the C42415655, from the RP2040/RP2350 family.
How big is the Avionics-Mainboard PCB?
The Avionics-Mainboard measures 90.2 × 95.9 mm, has 4 copper layers and is 1.69 mm thick.
How many components are on the Avionics-Mainboard?
316 components, from 98 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 Avionics-Mainboard design files?
From the cmu-argus-2/Avionics-Mainboard 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 Avionics-Mainboard design in my own project?
The repository has no license, so all rights stay with cmu-argus-2. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Avionics-Mainboard 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.
