5V isolated with MCU, effectively protecting the MCU; onboard 5V power indicator. Voltage indication at motor driver output; supports soldering of heat sink. Requires only four connections from MCU to driver module (GND, 5V, PWM1, PWM2); isolation chip powered by 5V supply (can be shared with MCU 5V). Enables motor direction reversal; two PWM inputs support up to 25kHz frequency; includes fault signal output.
