LED controller: common questions

What microcontroller does the LED controller use?

The LED controller is built around the STM32F107RCTx, from the STM32 family.

How big is the LED controller PCB?

The LED controller measures 122 × 87 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LED controller?

166 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the LED controller design files?

From the engineering-bay/LED_controller repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the LED controller design in my own project?

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

Can I test firmware for the LED controller 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.
