Developed based on STC32G12K128 chip Supports output modes with Hall. Control motor speed by changing input voltage or turning potentiometer knob Built-in potentiometer for speed adjustment, no external signal required. Uses 3 IR2101 gate drivers + 6 NCE6050 MOS tubes to form a brushless drive circuit, supports traditional brushless 6-step commutation method to control motor. Reserved burning port to support user secondary development. Chip:STC32G12K128 Power supply:DC12-24V (the power supply depends on the motor voltage) Limit current:10A (it is recommended to install a heat sink) Output mode:with Hall The product appearance and printed words depending on the batch, but this does not affect use.
