Dongle: common questions

What microcontroller does the Dongle use?

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

How big is the Dongle PCB?

The Dongle measures 67.3 × 40 mm and is 1.6002 mm thick.

How many components are on the Dongle?

39 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dongle 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 Dongle 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 Dongle 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.
