MotorInterfacePiPico: common questions

What microcontroller does the MotorInterfacePiPico use?

The MotorInterfacePiPico is built around the Pico, from the RP2040/RP2350 family.

How big is the MotorInterfacePiPico PCB?

The MotorInterfacePiPico measures 120.3 × 65.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MotorInterfacePiPico?

47 components, from 15 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 MotorInterfacePiPico design files?

From the rosstimo/MotorProject 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 MotorInterfacePiPico design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the MotorInterfacePiPico 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.
