Item Type: Motor Drive Module Function: Dual BTS7960 High Current (43 A) H-bridge driver; 5V is isolated from MCU to effectively protect MCU; Built-in 5V power indicator; Voltage indication at the output of the motor driver; The heat sink can be welded; PIN Definition: 1. RPWM: Right turn to PWM 2. LPWM: Left turn PWM 3. R_EN: Right turn to enable (active high) 4. L_EN: Enable left turn (active high) 5. R_IS: Right turn current warning (can float) 6. L_IS: Left turn current warning (can float) 7. VCC: (5V) 8. GND Connection Method: Method 1: VCC: 5V from single-chip computer (MCU) GND: GND of the microcontroller (MCU) L_PWM: PWM or 5V from the microcontroller (MCU) for CCW (CW) turns R_PWM: PWM or 5V from the microcontroller (MCU) for CW (CCW) turns R_EN and L_EN: 5V from the microcontroller (MCU) Method 2: VCC: 5V from single-chip computer (MCU) GND: GND of the microcontroller (MCU) L_PWM: 5V from the microcontroller (MCU) for CCW (CW) turns R_PWM: 5V from the microcontroller (MCU) for CW (CCW) turns R_EN and L_EN: PWM from the microcontroller (MCU) Only four wires (GND. 5V. PWM1. PWM2) are needed from the MCU to the drive module; Isolation chip 5V power supply (can be shared with MCU 5V); Can make the motor rotate forward, two PWM input frequencies up to 25kHZ; Two heat flows through a fault signal output; Isolation chip 5V power supply (can be shared with MCU 5V), you can also use the built-in 5V power supply; Power supply voltage 5.5V to 27V; 1The driver uses the BTS7960 chip, which consists of a high-power driven full H-bridge drive module with thermal overcurrent protection. 2The dual BTS7960 H-bridge drive circuit has powerful drive and braking functions, effectively isolating the microcontroller and the 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 computer can effectively protect the single-chip computer. 5The product is characterized by stable performance and long service life. 1 x Motor Drive ModulePlease note that the new type and old type of this product will be sent randomly, and make sure you don't mind before ordering.
