The cabinet houses 500+ 1/43rd scale model cars across 4 vertical sections, each lit by two 120-LED strips (960 LEDs total). Any USB host can control the LEDs. For this appication, the garage includes a Raspberry Pi with a touchscreen running a web interface to send LED colour data.

LED-Driver: common questions

What microcontroller does the LED-Driver use?

The LED-Driver is built around the C8317, from the STM32 family.

How big is the LED-Driver PCB?

The LED-Driver measures 244 × 142.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LED-Driver?

51 components, from 18 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 LED-Driver design files?

From the nicholasshort/LED-Driver 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 LED-Driver design in my own project?

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

Can I test firmware for the LED-Driver 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.
