Mattie: common questions

What microcontroller does the Mattie use?

The Mattie is built around the STM32F40X_LQFP64, from the STM32 family.

How big is the Mattie PCB?

The Mattie measures 55 × 32 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mattie?

55 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mattie design files?

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

Can I use the Mattie design in my own project?

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

Can I test firmware for the Mattie 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.
