A ton of ExpressLRS items are available now!

Recommend ExpressLRS Recovery Dongle for flashing or recovering the receiver.

Bullet Points

A true diversity receiver with two complete RF receiver chains (referring to dual SX1280/SX1281 or dual SX1276), based on the latest official ExprssLRS. It comes with ExpressLRS V3.0.0 firmware.
Ultralight weight is only 1.1g without the antenna. The receiver board features a reasonable layout and is impeccably clean. Very easy to solder.
Two Dipole T antennas will create an omnidirectional signal for good signal transmission. Placing the antenna separately and vertically as far apart as possible to get a better signal is recommended.
Not only it is used for FPV drones but also for FPV fixed-wing, or other FPV aircraft. It has superb performance in long-range flying.
The first true diversity receiver for the 915MHz/868MHz frequency bands, with two separate receiving modules working together to improve signal reception quality and overall reliability.
The 900MHz radio system exhibits greater diffraction ability due to its lower frequency, while the 2.4GHz systems tend to be directional and susceptible to attenuation caused by buildings, foliage, or moisture.

Diagram

The SuperD receiver 2.4GHz version diagram is shown below.

The SuperD receiver 915MHz/868MHz version diagram is shown below.

SuperD receiver RGB status indication is shown below.

RGB Color	Status	Description
Rainbow	Fade effect	Power on
Green	Slow 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.

2.4GHz:

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.

915MHz/868MHz:

Note: D50 is a unique mode of ELRS Team900. Under the 200Hz refresh rate of Lora mode, the same data packet is repeatedly sent four times, and the receiving distance is equivalent to 200Hz.

100Hz Full is a mode that realizes 16-channel full-resolution output at the 200Hz refresh rate of Lora mode, and the receiving distance is equivalent to 200Hz.

Configuration & Bind

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.

Power on and off the receiver 3 times, each step pausing 2 seconds to enter binding mode;
When the indicator starts fast blink with orange twice, the receiving is at binding mode;
Enter the radio or transmitter module's binding mode to bind with the receiver; if the Indicator has turned solid, it indicates that the device has been bound successfully.

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.

The 2.4GHz default firmware is ELRS V3.0.0. If you would like to bind with a remote control or transmitter module, please upgrade it to V3.0.0 or above. If you would like to flash the latest official ELRS firmware for the SuperD receiver, please upgrade ELRS Configurator to V1.5.2 or above. Select the target device "BETAFPV SuperD 2.4GHz RX".

The 915MHz/868MHz default firmware is ELRS V3.3.0. The official version has not yet been released. It will be updated synchronously with the ELRS V3.3 version. Then you can click the latest ELRS Configurator Nightly to operate. Select the target device ''BETAFPV SuperD 900MHz RX''.

Note: Firmware for 915MHz/868MHz is currently self-compiled firmware.

SuperD ELRS Diversity Receiver

Prestazioni della ricevente soddisfacente.

Good range and Link Quality

I use this with an ELRS 1-watt, 2.4 GHz Radiomaster Boxer at the edge of the city. I fly at 500 Hz "full" packet rate with around 1:8 telemetry rate. I use dynamic power up to 1-watt on the Boxer, and 100 mW telemetry power from the SuperD. On a visual range test flight where I reached 2.7 km in distance, the stats for the flight were as follows:
RSSI (ELRS, so higher is better): min = -88 dB max = -25 dB average = -67 dB
Received Link Quality (dynamic power from Boxer radio): min = 53% max = 100% average = 99%
Transmitted Link Quality (100 mW telemetry back to Boxer radio): min = 20% max = 100% average = 93.05%
Boxer Transmit power required during flight: min = 25 mW max = 1000 mW average = 320 mW

Overall, I'm very pleased with the performance of this. The only reason I had to turn around at a 2.7 km distance from home on this flight test was because I lost sight of the drone (airplane). I am sure that with a lower telemetry and packet rate, I could fly even further with a better connection. Updating the receiver firmware and binding with model match and bind phrase works flawlessly. My statistics begin logging as soon as I arm the drone, and they stop running as soon as I am disarmed, so they should be fairly accurate in terms of the averages.

Trees and diversity!

I don't think i've seen sub ninety seven link quality since i've had them.
The 2.4 diversity gives me about the same penetration as 915 single receiver under the forest canopy. The 915 diversity is a test in progress, it seems to never end.
