60A 2Way PWM DC Motor Driver Module: 9V - 30V High Power H - Bridge, Forward/Reverse Speed Adjustable DC 9V-30V 60A 2Way PWM DC Motor Driver Module Speed Controller High Power H-Bridge Forward/Reverse Speed Adjustable1.The basic components of this product for the SMD of integration, the module design is beautiful, well laid out, very small size, on-board two-way high-power DC motor drive 2. Wide heat sink can effectively dissipate heat for module when high current,to maintain the module's good stability performance 3. When driving the motor, the maximum rated current of the module can be up to 60A, and the on-resistance is only 0.003 ohm. 4. High switching frequency, up to 60KHZ, which effectively avoids the unpleasantness of debugging motor frequency is low. 5.3.3V and 5V microcontroller can control this module, and only need a motor power supply (12V - 30V) Input voltage: 9-30V Control interface: A.B=0.0 for brake A.B=1.0 for positive rotation A.B=0.1 for reverse rotation PA is PWM wave input (motor speed regulation) G is the common ground pin with the control board (B road for the same control) Positioning hole: 3mm Hole pitch: 52x42mm Colour:As Shown Material:PC Package Contents: 1 x Motor driver module(Due to different product batches, the appearance , which does not affect the use) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
