MPU MOD: common questions

What microcontroller does the MPU MOD use?

The MPU MOD is built around the STM32MP157FABx, from the STM32 family.

How big is the MPU MOD PCB?

The MPU MOD measures 50 × 70 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the MPU MOD?

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

Where can I download the MPU MOD design files?

From the Decktrix-Lab/decktrix repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MPU MOD design in my own project?

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

Can I test firmware for the MPU MOD 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.
