KI Maker Documentation


Download KI Maker manuals, specification sheets, wiring examples, and support documents for each board.

KI Maker documentation is written for practical low-voltage DC projects. Each document focuses on clear wiring rules, honest ratings, connection guidance, test points, limitations, and troubleshooting steps.

Always read the manual before applying power. KI Maker boards are low-voltage DC modules only and are not intended for AC mains, life-safety, medical, emergency-stop, automotive safety, or certified safety applications.


KI Maker PWR INTF Documentation

Power distribution, regulated rails, fan power, USB-C 5 V output, basic utility I/O, and accessory wiring for 18–30 VDC maker systems.
