Theory of Operation

The controller listens for messages on the CANbus and drives two addressable RGB LED strips and four general-purpose open-collector outputs. It also monitors four general-purpose inputs and can send CANbus messages or change outputs in response to events.

The outputs are rated for 1A each and are intended to drive LED lights, such as headlights, tail lights, etc. The inputs are active-high and intended for body sensors and switches, such as a door switch.

Questions

How big is the Led controller PCB?

It measures 80 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Led controller use?

86 parts, built around the ISO1042BQDWVQ1, ADG3308BRUZ, DMN3053L-7 and SMDA24C. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Led controller KiCad files?

From the codeThatThinks/autotank-led-hw repository on GitHub, at the commit this page was made from: the board is kicad/led-controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

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

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
