MotorDriver: common questions

What microcontroller does the MotorDriver use?

The MotorDriver is built around the DRV8701ERGET, from the RP2040/RP2350 family.

How big is the MotorDriver PCB?

The MotorDriver measures 101.4 × 73.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MotorDriver?

95 components, from 29 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 MotorDriver design files?

From the CharHanMaker/CharHanMaker 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 MotorDriver design in my own project?

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

Can I test firmware for the MotorDriver 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.
