BetaFPV ELRS Lite RX 2.4GHz - Flat Antenna V1.2

BetaFPV ELRS Lite RX 2.4GHz - Flat Antenna V1.2 is an ultra-light nano receiver with an integrated antenna for the ExpressLRS system at 2.4GHz. It is suitable for micro drones and racing drones where space is limited and every tenth of a gram counts. Version V1.2 features a thinner board with a thickness of 3mm, weighs only 0.46g (13.2% less than the previous version), and has enlarged solder pads for easier and less error-prone installation.

The receiver is built around ESP8285 (MCU) and SX1280 (RF) chips. It does not have a PA/LNA amplifier, so the telemetry output is 17mW, which is the native output of the RF chip. Instead of an external antenna, it has a flat SMD ceramic antenna directly on the board. Nothing protrudes from the receiver, so there is nothing to tear off even in a hard crash. In version V1.2, the manufacturer optimized the antenna impedance matching.
