MotCtrl: common questions

What microcontroller does the MotCtrl use?

The MotCtrl is built around the STM32F446R(C-E)Tx, from the STM32 family.

How big is the MotCtrl PCB?

The MotCtrl measures 76.7 × 44.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MotCtrl?

137 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the MotCtrl design files?

From the osannolik/MotCtrl repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MotCtrl design in my own project?

Yes, under the terms of its GPL-3.0 license, which osannolik chose for the repository.

Can I test firmware for the MotCtrl 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.
