Distorsion: common questions

What microcontroller does the Distorsion use?

The Distorsion is built around the STM32F407VGTx, from the STM32 family.

How big is the Distorsion PCB?

The Distorsion measures 126.4 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Distorsion?

129 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Distorsion design files?

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

Can I use the Distorsion design in my own project?

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

Can I test firmware for the Distorsion 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.
