BETAFPV SuperD ELRS 2.4G is the world's first True Diversity Receiver that applies two antennas, dual receiver chains, and TCXO (temperature compensated crystal oscillator) tech, achieving super accurate frequency rate and excellent performance in extreme temperature environments. It greatly fulfills the requirements of reliability for long range flying, aerial photography, or FPV freestyle tricks
Recommend ExpressLRS Recovery Dongle for flashing or recovering the receiver.
SuperD ELRS 2.4G Diversity Receiver is built-in a TCXO (temperature compensated crystal oscillator), which is shared by two RF chips for a super accurate clock source. The true diversity receiver including two RF chips and PA+LNA will generate a large amount of heat when working. With the high-quality TCXO, it can withstand extreme temperatures with no fear of heat and cold, continuously outputting accurate frequency for long range flight.
SuperD ELRS 2.4G Diversity Receiver has dual RF receiver chains with two antennas, ensuring longer and more stable flying for FPV drones and RC airplanes. Choosing a suitable receiver to fly quadcopter or other RC models is very important. BETAFPV ExpressLRS Receivers including ELRS Lite, Nano, Micro, and the newest SuperD, greatly fulfill pilots' requirements for FPV flying.

The diagram for SuperD ELRS 2.4G Diversity Receiver. Below picture is the front for RX.
The back of the RX is below.
SuperD receiver RGB status indication is shown below.
|Rainbow||Fade effect||Power on|
|Green||Quick flash||WIFI upgrading mode|
|Red||Quick flash||No RF chip detected|
|Orange||Double flash||Binding mode|
|Orange||Triple flash||Connected, but mismatched model-match configuration
|Orange||Slow flash||Waiting for connection|
|Solid on||Connected and color indicates packet rate|
The RGB light color corresponding to the packet rate is shown in the figure below.
Note: F1000 and F500 are packet rates in FLRC mode, providing faster modulation and lower latency, but at the same time having shorter reception distance than normal Lora mode. This mode is great for racers.
D500 and D250 are packet rates in DVDA (Deja Vu Diversity Aid) mode. This mode works at the F1000 data packet rate of FLRC mode, providing better link connection in the case of complex interference by sending the same data packet multiple times. D500 and D250 indicate that the same data packet is sent twice and four times respectively.
ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the SuperD diversity receiver and the flight controller board. Take the flight controller using the Betaflight firmware as an example to introduce its wiring and port configuration.
The connection between the SuperD diversity receiver and the flight controller is shown in the figure below
Connect the flight controller to the Betaflight Configurator for basic configuration. First, on the "Port" page, enable the flight controller serial port (take UART1 as an example) as "Serial Rx".
On the configuration page, set Receiver Mode to Serial (via UART) and Serial Receiver Provider to CRSF.
The default firmware of the SuperD diversity receiver uses the ExpressLRS V3.0.0 protocol and has no preset binding phrase. Therefore, the firmware version of the transmitter module must be ExpressLRS V3.0.0 or later versions. Both the receiver and transmitter module should not have any binding phrase.
Note: After binding once, the receiver will remember the autosaved binding phrase and device. Further restarting of the device will be bound automatically without the need for a rebinding process.
When binding the receiver, the duration for powering on/off should be 1 second each time, making sure the RGB not lighting.
If you would like to flash the official ExpressLRS V3.0.0 firmware for SuperD receiver, please upgrade ExpressLRS Configurator to V1.5.2. Select the target device "BETAFPV SuperD 2.4GHz RX"
