Submission: common questions

What microcontroller does the Submission use?

The Submission is built around the STM32F072CBT6, from the STM32 family.

How big is the Submission PCB?

The Submission measures 198.4 × 84.1 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the Submission?

101 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Submission design files?

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

Can I use the Submission design in my own project?

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

Can I test firmware for the Submission 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.
