Lab1: common questions

What microcontroller does the Lab1 use?

The Lab1 is built around the STM32F411RETx, from the STM32 family.

How big is the Lab1 PCB?

The Lab1 measures 54.5 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lab1?

25 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lab1 design files?

From the jsjolund/dmx512-controller-board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Lab1 design in my own project?

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

Can I test firmware for the Lab1 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.
