Features

  • Compatible with Crossfire Receivers Only
  • No 5V Regulator Built-in
  • Built-in Current Sensor
  • Failsafe Value AutoSet
  • Firmware Upgradeable
  • 6 PWM Outputs
  • 2 UARTS

PINOUTS AND PADS

  • 4v5 pad voltage = 5V pad voltage -0.3V, make sure the voltage on the 5V pad is not higher than receiver and GPS rated voltage.
  • Tx2/Rx2(UART2) for GPS/firmware update/setting parameters
  • Tx1/Rx1(UART1) for CRSF protocol Receiver
  • Vbat: Battery voltage sensing (0~36V)
  • Curr: current sensor signal (0~3.3V)
  • 1~10: CH1~CH10 PWM outputs
  • G: ground

FAILSAFE

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

LED STATUS

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

GPS TELEMETRY

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

TIM & PWM FREQUENCY

  • PWM frequency on all 10x Channels can be configured according to TIM
  • PWM runs at 50Hz by default
  • TIM3: CH5, CH6, CH7, CH8
  • TIM2: CH1, CH2, CH4
  • TIM1: CH9, CH10
  • TIM16: CH3

CLI MODE

  • If the CRSF-PWM board doesn’t detect GPS connected to UART2 within 10 seconds after powering on, CLI mode will active.
  • After CLI mode is active, the CRSF-PWM board can be connected to the configurator via USB-TTL module/FC passthrough.
  • CLI mode has no effect on receiver CRSF signal and PWM outputs
  • In CLI mode, CRSF-PWM board firmware can be updated

Specifications

  • Support: Any CRSF protocol receivers (including 433MHz, 868MHz, 915MHz, 2.4GHz)
  • Current sensor: Compatible with External (0-3.3V)
  • Telemetry ID: RxBt, Curr, Capa, Bat%, GPS, GSpd, Hdg, Alt, Sats
  • PWM frequency configurable (50Hz default, 100,160,330, 400Hz)
  • 36V Max. battery voltage sense (1K:10K voltage divider built-in)
  • Rated voltage: 4~9V @5V pad, 0~36V @vBAT, 0-3.3V Curr
  • Vbat and Current sensor scale configurable
  • UARTs (for Receiver and GPS): 2
  • Size: 25mm x 16mm
  • PWM outputs: 10
  • Weight: 1.3g

Includes

  • 1x MATEKSYS CRSF-PWM-6 Converter
  • 1x Dupont 2.54 Pins
