Product Description
Summary
ELRS 2.4G Diversity Receiver is a new generation of true dual-antenna diversity receiver system based on the ExpressLRS open source project. ExpressLRS features long range operation, low latency, maximum 1000Hz refresh rate, and low price.
The ELRS 2.4G Diversity Receiver has a reasonable placement of dual antennas for wider signal reception and more stable connection than ordinary single antenna receiver systems. It uses a TCXO temperature compensated crystal oscillator to avoid frequency shifts caused by temperature changes and the telemetry power is up to 100mW.
