SuSim SMC3 R4

The established SMC3 controller, reimplemented for the Arduino Uno R4.

The adapter PCB for Arduino R4

These CAD views show the layout of the connectors and pin headers. The connector side includes labels for the sensor, RJ45, MD13S and CAN. Select a view to enlarge it.

The views illustrate the layout. Wiring must follow the schematic for the corresponding board revision.

The idea

This project ports the established SMC3 approach from the Arduino Uno R3 to the Uno R4. It aims to provide a modern, understandable foundation for DIY motion rigs while retaining the strengths of the original concept.

Current status

Development and testing. Documentation, assembly guidance and technical details will follow once each step has been reliably tested.

For DIY builders

The implementation is intended to remain understandable and encourage building, learning and further development. SuSim is not a shop and does not offer commercial products.
