Seamlessly integrates with your Power Functions builds

Interface C is a Power Functions–compatible motor controller that brings six-speed precision—forward or reverse—at the twist of a dial. Prefer hands-off control? Pop it on your Wi-Fi and drive from a clean web interface in your browser on the local network. It’s fast, simple, and fun for layouts, displays, and testing.

Build your own

Print the case from the included .3mf/.stl files, source the electronics (see the Interface C documentation), and assemble. You can choose the path that fits your build style—from a PCB-only kit to a full kit with the Arduino Nano ESP32—all documented step by step.
