2Pcs High Power 43A Motor Driver Module for Arduino Smart Car with Current Limit Function

This driver uses BTS7960 chips, a high-power full H-bridge driver module with thermal and over-current protection. It features a dual BTS7960 H-bridge driver circuit for strong drive and braking capability, providing effective isolation between the microcontroller and motor driver. Key Features: - High-current capacity: 43A per channel - 5V isolation from MCU for enhanced protection - On-board 5V power indicator - Motor driver output voltage indication - Heat sink mounting option PIN Definitions: 1. RPWM: Right PWM input 2. LPWM: Left PWM input 3. R_EN: Right enable (high active) 4. L_EN: Left enable (high active) 5. R_IS: Right current sense output (can be left floating) 6. L_IS: Left current sense output (can be left floating) 7. VCC: 5V power supply input 8. GND: Ground Connection Options: Method 1: - VCC: 5V from MCU - GND: Ground from MCU - LPWM: PWM or 5V signal from MCU for counter-clockwise (or clockwise) rotation - RPWM: PWM or 5V signal from MCU for clockwise (or counter-clockwise) rotation - R_EN and L_EN: 5V signals from MCU Method 2: - VCC: 5V from MCU - GND: Ground from MCU - LPWM: 5V signal from MCU for counter-clockwise (or clockwise) rotation - RPWM: 5V signal from MCU for clockwise (or counter-clockwise) rotation - R_EN and L_EN: PWM signals from MCU Only four connections required from MCU to driver (GND, 5V, PWM1, PWM2). - Isolation circuit powered by 5V (can share MCU 5V supply) - Supports bidirectional motor control (forward/reverse) - PWM input frequency up to 25 kHz - Current sense outputs for monitoring - Input voltage range: 5.5V to 27V - Color: Blue and black - Material: PCB - Dimensions: 4 x 5 x 1.2 cm Package Includes: - 2 x BTS7960B H-bridge 43A high-power motor driver modules Note: Colors may vary slightly due to lighting and screen settings. Dimensional tolerance: ±1–3 cm.
