Main: common questions

What microcontroller does the Main use?

The Main is built around the STM32F405RXT, from the STM32 family.

How big is the Main PCB?

The Main measures 100 × 100 mm and is 1.6002 mm thick.

How many components are on the Main?

186 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main 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 Main 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 Main 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.
