Ribbon Controller Main Board: common questions

What microcontroller does the Ribbon Controller Main Board use?

The Ribbon Controller Main Board is built around the STM32L412K8UX, from the STM32 family.

How big is the Ribbon Controller Main Board?

The Ribbon Controller Main Board measures 147.7 × 31.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ribbon Controller Main Board?

71 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ribbon Controller Main Board design files?

From the JordanAceto/rust_ribbon_controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Ribbon Controller Main Board design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which JordanAceto chose for the repository.

Can I test firmware for the Ribbon Controller Main Board 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.
