5V isolate with MCU, and effectively protect MCU
5V power indicator on board.
Voltage indication of motor driver output end
can solder heat sink.
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).
Able 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.
