Custom Product Tab

Featuring dual-channel 2.4GHz radios, the RP4TD excels in signal sensitivity, signal-to-noise ratio, and overall performance due to its optimized circuit design. The reliable DCDC power supply circuit ensures lower operating temperatures during extended usage. Additionally, the dual TCXO contributes to the utmost frequency stability and makes the RP4TD a leader in its class. 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.

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

Dual 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. In our testing, we found that two TCXOs offer better advantages in true diversity receivers.

The RP4TD is now compatible with mLRS!

The mLRS project offers an open source 2.4 GHz & 915/868 MHz & 433 MHz/70 cm LoRa-based high-performance long-range radio link, which provides bidirectional serial connection combined with full remote control.

The 'm' in the project name alludes to 'Mavlink', as it will have features which optimizes performance for Mavlink systems. However, it always will also provide a transparent serial link and hence will be of wider use and not be limited to Mavlink systems only. The 'LR' in the project name alludes to 'long range', which however should not be understood in terms of an absolute range, like 100 km, but - of course - as the best possible range under the given conditions. Physical laws simply say that the higher the data rate the shorter the range. So, mLRS cannot compete range-wise with systems which achieve their range by reducing data rate to a minimum, at the cost of the resulting compromises. The goal of mLRS is to achieve a high range under the condition of a relatively high data rate.
