Bts7960 43a High Power Motor Driver Module/smart Car Driver Module For Current Limit 5V isolate with MCU, and effectively protect MCU; 5V power indicator on board.Voltage indication of motor driver output end; can solder heat sink.Just need four lines from MCU to driver module (GND. 5V. PWM1. PWM2); isolation chip 5 V power supply (can share with MCU 5 V).Able to reverse the motor forward, two PWM input frequency up to 25kHZ; two heat flow passing through an error signal output.Isolated chip 5V power supply (can be shared with the MCU 5V), can also use the on-board 5V supply; the supply voltage 5.5V to 27V.Input voltage: 6V-27VMaximum current: 43AInput level: 3.3-5VControl method: PWM or levelDuty cycle: 0-100%Input port:1.RPWM: forward level or PWM signal input, active high2.LPWM: Reverse level or PWM signal input, active high3.R_EN: forward drive enable input, high-level enable, low level off4.L_EN: Reverse drive enable input, high-level enable, low level off5.R_IS: forward drive current alarm output6.L_IS: Reverse drive current alarm output7.VCC: +5 V power output, 5V power supply connection with the microcontroller8.GND: signal common low endColour:Photo ColorMaterial: ABSSize: 5 x 5 x 3cmPackage Contents:1 x Motor Driver ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
