Note: A Hall driver board requires a motor with Hall to function properly. Without a Hall driver board, both Hall and non-Hall motors can be used. Starting smoothness is improved with a Hall driver BLDC wide voltage 6-60V, 400W power, three-phase brushless DC controller; supports Hall or non-Hall controller. Features include PLC 0-5V analog speed control, forward and reverse control, and PWM ratio speed regulation. Suitable for 120-degree electrical angle DC brushless motors with or without Hall Due to different production batches, product appearance and color may vary slightly, but this does not affect normal use Type: with Hall Color: red Material: PCB Package Contents: 1 x Driver Board (other items not included) Note: Lighting effects and display differences may cause slight color variations between the image and actual item. Measurement error allowance is +/- 1-3cm.
