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);
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;
