Electrodragon 7CH PWM ELRS Receiver

Electrodragon ELRS 2.4G Receiver, Seven-Channel PWM Receiver

This receiver features independent PWM channel outputs, suitable for fixed-wing aircraft, cars, boats, and other models. It also supports CRSF output. The two output signals (PWM and CRSF) can be switched without re-flashing the firmware.

Follow these steps to switch between PWM (6CH/7CH) and CRSF modes:

Accessing the Receiver's Wi-Fi Network:

  1. If connected to the high-frequency head (transmitter module): Use the transmitter's LUA script menu to activate the receiver's Wi-Fi.
  2. If not connected to the high-frequency head: Power on the receiver and wait for one minute. The receiver will automatically enter Wi-Fi mode.

Connecting to the Receiver's Wi-Fi:

  • Search for Wi-Fi networks on your computer or phone.
  • Wi-Fi Hotspot Name (SSID): EXPRESSLRSRX
  • Connection Password (all lowercase): expresslrs

Accessing the Configuration Page:

  • Open a web browser and go to: http://10.0.0.1/hardware.html

Configuring the Receiver:

  • This will take you to the ELRS hardware configuration page where you can import hardware configuration files.
  • Caution: Do not modify parameters yourself unless you fully understand their meaning.
  • Import the provided configuration file for either PWM7CH or CRSF.
  • Click the button at the bottom of the page and wait for the receiver to restart automatically.
