Description
MICROSPORA is designed to compatible with SimpleFOC firmware, suitable for projects requiring high-performance motor control.
Firmware: https://github.com/rambros3d/MicroSpora-SimpleFOC
Example: Spring back to position
This is SimpleFOC Position mode running on MicroSpora. The motor always returns to its default position, providing a spring-like feel when moved. SimpleFOC adjusts the coil PWM to exert an opposing force on the motor when it is disturbed from its original position. This behavior is visualized on the BLDC led visualizer.
