SEQURE ELRS 2.4GHz Single RX Single Antenna Receiver

SEQURE ELRS 2.4GHz Single RX Receiver with Single Antenna (80mm)

The SEQURE ELRS 2.4GHz Single RX is a compact, lightweight receiver designed for RC pilots who want reliable ExpressLRS performance, fast response, and stable telemetry in a tiny form factor. Built for hobby-grade FPV and racing setups, it combines strong interference resistance, low latency, and flexible installation options.

Key features:

• Operates on the 2.4GHz band for strong anti-interference performance and solid signal penetration.
• Supports ultra-fast F1000Hz and F500Hz refresh rates for low-latency control, ideal for racing and demanding FPV flying.
• Built-in TCXO (temperature-compensated crystal oscillator) helps maintain stable operation across changing temperatures.
• Integrated high-power PA + low-noise LNA with 100mW (20dBm) telemetry for more stable in-flight data transmission.
• Supports both SH1.0-4P connector and 2.54-4P pads for flexible wiring and easy integration into different builds.
• Single antenna design with IPEX1 antenna interface.
• Compact and ultra-lightweight construction, perfect for space-sensitive RC and FPV projects.
