README
README.mdWelcome to the Can LED Driver Git repo!
This is an STM32 based smart load switch that is capable of driving up to 60A at 20V (ignoring thermals) Currently it is just a hardware repo - software TBC. I know it is overkill but that is more fun than simplicity :seal:

Questions
How big is the CLD PCB?
It measures 48.5 × 40.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CLD use?
40 parts, built around the MCP2551-I/SN-HG, FAN3111ESX, AP2112K-3.3 and BSC072N08NS5. 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 CLD KiCad files?
From the JackUlbrichBaker/CLD repository on GitHub, at the commit this page was made from: the board is CLD/CLD.kicad_pcb and its schematic CLD/CLD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CLD design in my own project?
Its repository states no licence, so its author keeps all rights: ask JackUlbrichBaker before reusing the design.

The main ICs are an mcu, and a 5v 2a switching regulator. The system can theoretically handle 20 volt spikes, but this is mostly meant for 5v output on one side only.
