RPWM: Turn right to PWM_x000D_2. LPWM: Turn left PWM_x000D_3. R_EN: Turn right to enable (active high)_x000D_4. L_EN: Enable left turn (active high)_x000D_5. R_IS: Right turn current warning (may float)_x000D_6. L_IS: Left-turn current warning (may float)_x000D_7. VCC: (5V)_x000D_8. GND_x000D_Connection Method:_x000D_Method 1:_x000D_VCC: 5V from single chip microcomputer (MCU)_x000D_GND: GND of the microcontroller (MCU)_x000D_L_PWM: PWM or 5V from the microcontroller (MCU) for CCW (CW) turns_x000D_R_PWM: PWM or 5V from microcontroller (MCU) for CW (CCW) turns_x000D_R_EN and L_EN: 5V from the microcontroller (MCU)_x000D_Method 2:_x000D_VCC: 5V from single chip microcomputer (MCU)_x000D_GND: GND of the microcontroller (MCU)_x000D_L_PWM: 5V from the microcontroller (MCU) for CCW (CW) turns_x000D_R_PWM: 5V from the microcontroller (MCU) for CW (CCW) turns_x000D_R_EN and L_EN: PWM from microcontroller (MCU)_x000D_Merely four wires (GND. 5V. PWM1. PWM2) are needed from the MCU to the driver module;_x000D_Isolation chip 5 V power supply (can be shared with MCU 5 V);_x000D_Can make the motor rotate forward, two PWM input frequencies up to 25kHZ;_x000D_Two heat flows through an error signal output;_x000D_Isolation chip 5V power supply (can be shared with MCU 5V), you can also use the onboard 5V power supply;_x000D_Power supply voltage 5.5V to 27V; 1The driver uses the BTS7960 chip, which consists of a high-power drive full H-bridge driver module with thermal overcurrent protection. 2The dual BTS7960 H-bridge driver circuit has powerful driving and braking functions, effectively isolating the microcontroller and motor driver and high current 43A. 3This product can realize forward and reverse rotation of the motor, and the two PWM inputs have a maximum frequency of 25kHZ. 45V isolation from the single chip can effectively protect the single chip. 5The product is featured with stable performance and long service life.1 x_x000D__x000D_Motor Drive ModulePlease note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
