Underglow2-remote: common questions

What microcontroller does the Underglow2-remote use?

The Underglow2-remote is built around the STM32G431CBU6, from the STM32 family.

How big is the Underglow2-remote PCB?

The Underglow2-remote measures 88 × 123.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Underglow2-remote?

60 components, from 38 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 Underglow2-remote design files?

From the ConnorRigby/underglow2 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 Underglow2-remote design in my own project?

Yes, under the terms of its Apache-2.0 license, which ConnorRigby chose for the repository.

Can I test firmware for the Underglow2-remote 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.
