BTS7960 43A Dual H-Bridge Stepper Motor Drive Current Limiting Semiconductor Cooling 5V insulation with MCU, effectively protect the MCU; 5V power indicator on board. Voltage indicator at the output end of the motor driver, can solder the heat sink. You only need four wires from the MCU to the driver module (GND. 5 V PWM1 PWM2); insulation chip 5 V power supply (can be shared with MCU 5 V) Can rotate the motor forward and backward, two PWM input frequencies up to 25 kHz; two heat currents supplied via a fault signal output. Isolated chip 5V power supply (can be shared with the MCU 5V), can also be the built-in 5V supply, the supply voltage is 5.5V to 27V.
