The Radiomaster RP3 V2 ExpressLRS 2.4GHz Nano receiver is equipped with the SX1281 RF chip, which provides stable signal reception in the 2.404-2.479GHz band. The built-in power amplifier (PA) improves the telemetry range, and the low-noise amplifier (LNA) ensures high receiver sensitivity. The built-in TCXO minimizes frequency deviations with temperature changes, which improves communication stability. Two 65mm T-shaped antennas increase reception efficiency and reduce the likelihood of signal loss. The maximum reception refresh rate reaches 500Hz/F1000Hz, which ensures fast system response. The optimized PCB contributes to efficient heat dissipation during long-term operation. The device supports the CRSF interface and runs on ExpressLRS v3.0 firmware, which ensures compatibility with modern control systems.
