From the project

Open source RC platform

Description --- EasyRC is an easy-to-build platform for creating your own remote-controlled vehicle. The platform includes CAD files for printing an affordable 1:16 scale car as well as a small remote control. Further, it includes the project and production files for the printed circuit boards that are needed to power these devices. Last but not least, it lists all required components in a bill of materials and comes with a complete instruction manual that shows how to print, solder, assemble, program, and adjust everything for running the car. The legacy folder contains data and information…
