Tinymovr config


Make sure to set the motor type to gimbal (1) At the resistance and inductance values properly when setting up a new motor. As it can potentially fry the motor while calibrating.

The actual phase to phase resistance I measured was 2.3Ω on my purchased motor.

Measure each motor before setting the value on the tinyMovr board.
