3ch motor control: common questions

What microcontroller does the 3ch motor control use?

The 3ch motor control is built around the AP7375, from the STM32 family.

How big is the 3ch motor control PCB?

The 3ch motor control measures 75 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 3ch motor control?

62 components, from 31 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 3ch motor control design files?

From the Netetra/kicad-archive 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 3ch motor control design in my own project?

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

Can I test firmware for the 3ch motor control 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.
