Breakbeam processor: common questions
What microcontroller does the Breakbeam processor use?
The Breakbeam processor is built around the STM32F405RXT, from the STM32 family.
How big is the Breakbeam processor PCB?
The Breakbeam processor measures 96.5 × 52.1 mm and is 1.6002 mm thick.
How many components are on the Breakbeam processor?
46 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Breakbeam processor design files?
From the UBC-Thunderbots/Electrical repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Breakbeam processor design in my own project?
The repository has no license, so all rights stay with UBC-Thunderbots. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Breakbeam processor 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.
