PWM output settings The ELRS PWM receiver can enter the configuration interface through WIFI, and set parameters such as PWM channel, refresh frequency, and runaway protection. Specific steps are as follows: The receiver is powered on and waits for 60S, the receiver light flashes quickly, connect to the WIFI hotspot (ExpressLRS RX) password expresslrs, and automatically enter the setting interface.
