BETAFPV SuperD ELRS 2.4G Diversity Receiver

Note: F1000 and F500 are FLRC mode packet rates, which provide faster modulation and lower latency, but at the same time shorter range than regular LoRa mode. This mode is perfect for racers.

D500 and D250 are the packet rates in DVDA (Deja Vu Diversity Aid) mode. This mode operates at the data rate of FLRC mode F1000, thus providing better communication in case of complex interference. D500 and D250 indicate that the same data packet is sent two and four times respectively.

Configuration and pairing:

ExpressLRS uses the Crossfire serial protocol (also known as CRSF protocol) to communicate between the SuperD diversity receiver and the flight controller board. Take a flight controller running Betaflight software as an example to familiarize yourself with its wiring and port configuration.

Connect the flight controller to the Betaflight Configurator for a simple configuration. First, on the Port page, enable the flight controller's serial port (take UART1 as an example) as Serial Rx.

On the configuration page, set the Receiver Mode to Serial (via UART) and the Serial Receiver Provider to CRSF.

The default firmware of the SuperD diversity receiver uses the ExpressLRS V3.0.0 protocol and does not have a predefined binding phase. Therefore, the firmware version of the transmitter module must be ExpressLRS V3.0.0 or later. There must be no binding phase in either the receiver or transmitter module.

• Turn the SuperD diversity receiver on and off three times with a 1 second interval between each continuously to enter pairing mode.
• The RGB indicator on the SuperD diversity receiver will blink twice quickly, indicating that the receiver is in pairing mode.
• Configure the remote control or transmitter module to pair with the receiver; If the RGB indicator on the receiver is constantly on, it means the receiver is successfully paired.

Note: Once paired, the receiver will remember the automatically saved pairing phase and device. The next time you restart the device, it will be paired automatically, without having to go through the pairing process again.

When binding the receiver, the on/off duration should be 1 second each time, make sure the RGB is not lit.

To enable the official ExpressLRS V3.0.0 firmware for SuperD receiver, please update ExpressLRS Configurator to V1.5.2. Select the target device “BETAFPV SuperD 2.4GHz RX”
