BetaFPV SuperD ELRS Diversity Receiver

SuperD ELRS Diversity Receiver

BetaFPV’s new SuperD ELRS 2.4G Diversity Radio Receiver has dual RF receiver chains with two antennas, ensuring longer and more stable flying for FPV drones and other RC flying machines. It is equipped with two T-type antennas, just like the Happymodel EP1.

The BetaFPV SuperD ELRS RX module measures 22x14mm and weighs about 1 gram without the antennas. It features an ESP32-PICO-D4 processor with a dual SX1280 low-power 2.4G RF chip. According to the manufacturer’s specifications, the telemetry power is 100mW.

BetaFPV claims that the SuperD is the world’s first ExpressLRS true diversity receiver with a built-in 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 flights.

Main features

  • A true diversity receiver with two complete RF receiver chains (referring to PA+LNA+SX1280), 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 as possible to get a better signal is recommended.
  • It is not only used for FPV drones but also for FPV fixed-wing or other FPV aircraft. It has superb performance in long-range flying.
