Motor Drivers: common questions

What microcontroller does the Motor Drivers use?

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

How big is the Motor Drivers PCB?

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

How many components are on the Motor Drivers?

164 components, from 41 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 Motor Drivers 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 Motor Drivers 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 Motor Drivers 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.
