RadioMaster RP4TD ExpressLRS 2.4 GHz nano-receiver

RadioMaster RP4TD ExpressLRS 2.4 GHz nano-receiver

Equipped with dual-channel 2.4 GHz radios, the RP4TD excels in signal sensitivity, signal-to-noise ratio and overall performance thanks to its optimized circuit design. Reliable DCDC power circuit ensures lower operating temperatures during long-term use. Additionally, dual TCXO ensures the highest frequency stability and makes the RP4TD a leader in its class. The RP4TD has built-in Wi-Fi functionality, so you can wirelessly update firmware and configure the receiver via the built-in WebUI using your computer or mobile phone.

Suitable for drones and fixed-wing aircraft models, the receiver can be installed in virtually any application that requires a serial receiver!

Dual TCXO (Temperature Compensated Crystal Oscillator)

TCXO ensures high stability and accuracy of frequency control, compensating for temperature changes. This ensures consistent and reliable signal reception, even in extreme temperatures. It also reduces frequency drift over time, ensuring long-term frequency stability and preventing signal degradation. In our tests, we found that two TCXOs offer better benefits in True Diversity receivers.
