RadioMaster RP4TD ELRS 2.4GHz Receiver

The RadioMaster RP4TD is a 2.4GHz ExpressLRS receiver featuring true dual-chain diversity for maximum link reliability. By utilizing twin SX1281 RF chips, it simultaneously monitors both antennas to eliminate dropouts in signal-dense urban environments, concrete bandos, and long-range FPV flights.

Key features

• True diversity architecture with dual SX1281 RF chips for continuous twin-signal processing

• Integrated TCXO (Temperature Compensated Crystal Oscillator) ensures frequency stability across extreme flight temperatures

• ESP32 MCU delivering fast processing for ELRS V3.3.0 and newer firmware

• Includes dual 2.4GHz T-antennas for flexible perpendicular mounting configurations

Specifications

• MCU: ESP32

• RF Chip: Dual SX1281

• Telemetry Power: 100mW (20dBm)

• Antenna Connector: 2x IPEX1 (U.FL)

• Input Voltage: 4.5V - 8.4V

• Dimensions: 23.7 x 16.3 x 4.0 mm

• Weight: 1.4g (without antennas)

With a wide 4.5V to 8.4V input range, the RP4TD can be wired directly to standard 5V flight controller pads or higher voltage BECs. This receiver is highly recommended for freestyle frames flying behind heavy obstacles or cinematic rigs requiring an uncompromising control link.
