2. SIAYQ72180 sine wave motor controller with LIN
SIAYQ series controller is sine wave type controller, which is brushless DC controllerwith self-learning function. Generally, it matches well with QS Motors, if you want to match with new brand motor, some parameters should be tested by yourself.
Pls note that the FarDriver controller defaults to the Hall state, which cannot match the speedometer in the one-line state, like the DKD speedometer.
