Break light: common questions

What microcontroller does the Break light use?

The Break light is built around the STM32F103C8Tx, from the STM32 family.

How big is the Break light PCB?

The Break light measures 64 × 64 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Break light?

61 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Break light design files?

From the ncku-formula-racing/circuit repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Break light design in my own project?

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

Can I test firmware for the Break light 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.
