How big is the RPI-RP2350A-MINIMAL R4-S1 PCB?

The RPI-RP2350A-MINIMAL R4-S1 measures 52 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RPI-RP2350A-MINIMAL R4-S1?

39 components, from 19 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 RPI-RP2350A-MINIMAL R4-S1 design files?

From the TheronRogers/bee-whoop-tailsitter 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 RPI-RP2350A-MINIMAL R4-S1 design in my own project?

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

Can I test firmware for the RPI-RP2350A-MINIMAL R4-S1 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.
