PiCubed: common questions
What microcontroller does the PiCubed use?
The PiCubed is built around the RP2350_80QFN, from the RP2040/RP2350 family.
How big is the PiCubed PCB?
The PiCubed measures 90.2 × 95.9 mm, has 4 copper layers and is 1.6012 mm thick.
How many components are on the PiCubed?
176 components, from 74 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 PiCubed 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 PiCubed 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 PiCubed 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.
