Unified: common questions

What microcontroller does the Unified use?

The Unified is built around the STM32F030-32, from the STM32 family.

How big is the Unified PCB?

The Unified measures 48.3 × 20.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Unified?

39 components, from 32 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 Unified design files?

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

Can I use the Unified design in my own project?

The repository has no license, so all rights stay with ervanalb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Unified 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.
