Mdrv: common questions

What microcontroller does the Mdrv use?

The Mdrv is built around the STM32G474RETx, from the STM32 family.

How big is the Mdrv PCB?

The Mdrv measures 60 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mdrv?

112 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mdrv design files?

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

Can I use the Mdrv design in my own project?

Yes, under the terms of its MIT license, which hanneskiene chose for the repository.

Can I test firmware for the Mdrv 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.
