ArmTrax OG: common questions

What microcontroller does the ArmTrax OG use?

The ArmTrax OG is built around the STM32F103C8Tx, from the STM32 family.

How big is the ArmTrax OG PCB?

The ArmTrax OG measures 93.6 × 32 mm and is 1.6 mm thick.

How many components are on the ArmTrax OG?

92 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the ArmTrax OG design files?

From the embeddedalpha/PCB-Design repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ArmTrax OG design in my own project?

Yes, under the terms of its MIT license, which embeddedalpha chose for the repository.

Can I test firmware for the ArmTrax OG 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.
