The ER5A V2 receiver leverages the ExpressLRS 2.4GHz protocol to deliver ultra-low latency, high-resolution control, and extended range for RC aircraft and FPV drones. Its optimized PCB design ensures robust signal integrity and resistance to interference in demanding RF environments.
Engineered for versatility, it automatically selects between an external battery source or the receiver’s own BEC supply for accurate voltage telemetry back to the transmitter, a critical feature for monitoring flight pack health. The built-in TCXO maintains precise frequency control across a wide temperature range, ensuring consistent link performance.
