Control board: common questions

What microcontroller does the Control board use?

The Control board is built around the STM32G071CBUx, from the STM32 family.

How big is the Control board?

The Control board measures 48.5 × 48.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Control board?

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

Where can I download the Control board design files?

From the paradise-fi/RoFI repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Control board design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Control 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.
