    • 4v5 pad voltage = 5V pad voltage -0.3V,  make sure the voltage on 5V pad is not higher than receiver and GPS rated voltage.

    Failsafe (FW 1.1.1 or older)

    • Failsafe value is set automatically after CRSF-PWM board is powered on and receive CRSF signal. LED blinks 8 times quickly.
    • Failsafe value = The PWM value of each channel(except CH3) when CRSF signal is received by CRSF-PWM board for the first time
    • CH3 is specially arranged for the throttle,  Failsafe value = 988 by default.
    • Usually put the Throttle  joystick to the lowest point,  put AIL(Roll), ELE(Pitch), RUD(Yaw) middle before powering on receiver.

    Failsafe (FW 2.0.0 or newer)

    • CH3 is arranged for the throttle,  Failsafe value = 988 by default.  you can change the failsafe value of CH3 and other channels by following settings.
    • Make sure ESC signal is disconnected from CRSF-PWM board before starting failsafe settings
    • Bridge PWM1 and PWM2 signal pad, then power on CRSF-PWM board and receiver.
    • Failsafe value will be saved automatically after CRSF-PWM board is powered on and receive CRSF signal. LED blinks 8 times quickly.
    • Failsafe value = The PWM value of each transmitter channel when CRSF signal is received by CRSF-PWM board.
    • Remove the jumper between PWM 1 and 2,  then CRSF-PWM board will work in normal PWM output mode.

    LED status

    • slow blinks: CRSF-PWM board doesn’t receive CRSF signal, e.g., receiver is not bound with transmitter, receiver is not connected to UART1 of CRSF-PWM board.
    • 8x quick blinks: CRSF-PWM board received CRSF signal and failsafe value is saved. (firmware 1.1.1 or older)
    • solid ON:  CRSF-PWM board and receiver are working normally
    • 2x slow blinks between 8x fast blink and solid on: CLI mode is active  (firmware 1.1.1 or older)

    GPS telemetry

    • Compatible with GPS NMEA protocol, 1Hz, Baud 9600~115200
    • GPS “TX” to CRSF-PWM board “RX” Single wire half duplex UART connection,   CRSF-PWM board “TX” to GPS “RX” is not essential.
    • Support GPS Telemetry ID: GPS, GSpd, Hdg, Alt, Sats
    • u-blox series GPS can output “0+1 – UBX+NMEA” protocol by default
    • Sensors(GPS, GSpd, Hdg, Alt, Sats) will blink in Transmitter TELEMETRY tab once CRSF-PWM board has connection with GPS.
    • Troubleshooting for no GPS telemetry,  double check the wiring between GPS and CRSF-PWM board,  some u-blox GPS may don’t output NMEA protcol, you need to revert GPS to default configuration in u-center.
    • with OpenTX Telemetry Logging, You can plot your flight path or search the lost plane.

    • For using external current sensor on CRSF-PWM-6, You can adjust this value to match with the scale of external current sensor.

    set output_5 = ch[x](5/11/12)

    • output_5 pin is defined as CH5(AUX1) by default,   ELRS AUX1(CH5) is 1-bit / 2-position channel.
    • In ELRS 2.0 Wide switch mode, AUX2-AUX8(CH6~CH12) are 7-bit (128 position) for telemetry ratios 1:128 through 1:8, or 6-bit (64 position) for 1:4 and 1:2.
    • with this CLI command, You can remap AUX7(ch11) or AUX8(ch12) signal to output_5 pin of CRSF-PWM board.  then you will get 128-position channel instead of 2-position on “output 5” pin
