Radiomaster RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver Dual-Antenna

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.

TCXO (temperature compensated crystal oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation.
