Dc motor board: common questions

What microcontroller does the Dc motor board use?

The Dc motor board is built around the STM32G070RBTx (LQFP-64), from the STM32 family.

How big is the Dc motor board?

The Dc motor board measures 91.6 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dc motor board?

113 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dc motor board design files?

From the borzeman/PzbElectronics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dc motor board design in my own project?

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

Can I test firmware for the Dc motor board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
