Description

The Radiomaster RP4TD-M is a 2.4GHz ExpressRLS true diversity receiver and is compatible with all 2.4GHz ExpressLRS transmitters on the market.

Introducing the Compact and Lightweight RP4TD-M! Building on the success of the RP4TD, we’re excited to unveil the RP4TD-M—a compact and lightweight version designed for optimal performance. Weighing in at just 1 gram, this receiver is ideal for builds where minimizing weight is crucial, while still leveraging ‘Gemini’ technology for superior interference mitigation. Thanks to its optimized circuit design, the RP4TD-M features dual-channel 2.4GHz radios, delivering exceptional signal sensitivity, signal-to-noise ratio, and overall performance. Whether you’re into racing drones or any application where every gram counts, the RP4TD-M stands out as a leader in its class.

Features

  • Mini size true diversity Gemini receiver
  • Class leading SNR and RSSI performance
  • Built-in TCXO (temperature compensated crystal oscillator)
  • Optimized PCB design for better heat dissipation
  • Upgraded antenna with greater durability and performance
  • 2 x 10mW RF Telemetry power output
  • Compatible with all 2.4GHz ExpressLRS modules and transmitters with built in 2.4GHz ExpressLRS
Firmware Options: LBT & FCC – please select as required.
Gemini Mode: Using Gemini Mode the radio broadcasts two separate transmit chains on slightly difference frequencies, simultaneously, to send control information to a Gemini compatible receiver twice. This helps to ensure even greater signal stability, as you effectively have two RC links. If one signal gets blocked then there’s a chance the other will still be received.
