The Radiomaster RP4TD is a 2.4GHz ExpressRLS true diversity receiver and is compatible with all 2.4GHz ExpressLRS transmitters on the market.
The RadioMaster RP4TD is the first diversity receiver with two SX1281 RF chips. Featuring dual-channel 2.4GHz radios, the RP4TD excels in signal sensitivity, signal-to-noise ratio, and overall performance due to its optimised circuit design. Both SX1281 2.4GHz radio’s are bundled with a TCXO to prevent any frequency drifts that can occur when temperature varies to offer the best possible range and performance. The reliable DCDC power supply circuit ensures lower operating temperatures during extended usage.
The RP4TD offers a maximum of 2x 100mW Telemetry output power for your telemetry downlink. It supports a maximum receive refresh rate of 500Hz/F1000Hz, allowing for rapid and precise control inputs.
The RP4TD features built in WIFI so you can wirelessly upgrade firmware to configure the receiver via the built-in WebUI with your PC or mobile phone.
Designed to be versatile and compatible, the RP4TD Receiver can be installed in virtually any application that requires a serial receiver! It operates on a working voltage of 4.5-12V and weighs just 1.4g (without an antenna), ensuring minimal impact on your aircraft’s weight. The compact dimensions of 23.70 x 16.30 x 4.00mm make it suitable for even the tightest installations.
