Features: Support wide voltage range of 9-36V, and the maximum sustain load current is 12A (without heat dissipation), 15A (simple heat dissipation) and 20A (thick large radiator). Similar to L298 drive-logic, it can control speed regulation, forward and reverse rotation and braking by three line. Full PWM is supported, and the forward and reverse rotation can be directly controlled by keys The effective range of PWM is 0.1%-100.0%. It can provide 5V power supply for controllers such as single chip microcomputer, and has 5V output overcurrent protections and access signal overvoltage protections. Specifications: Material:ABS Power supply voltage: 6V-36V Control signal high level voltage: 2.0V-5.5V Low level voltage of control signal: 0V-0.8V, and 0V when suspended. PWM effective range: 0.1% ~ 100.0% PWM signal frequency range: 0~100KHz (20KHz recommended) The minimum effective PWM pulse width: 200ns. Operating temperature: -25-80 Length:Approx.55mm/2.16inches Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Package includes: 1x Motor Driver Board
