Smooth Operation

Switched from a square-wave controller to this FOC board. The difference in noise and efficiency is night and day. Very satisfied with the purchase.

Excellent for EV Prototyping

This board handled my 48V hub motor perfectly. The FOC implementation is smooth and the current sensing is accurate. Highly recommend for electric bike projects.

Runs Hot at Max Load

Works great at 10A, but gets warm near the 20A limit without active cooling. Make sure to add a fan if pushing maximum current continuously.

Solid Hardware, Docs Need Work

The hardware quality is top-notch and it runs cool under moderate load. However, the example code could use more comments for beginners.
