The RP1 ExpressLRS 2.4GHz Nano Receiver is designed to offer precise and reliable control for a wide range of remote-controlled models. Its small form factor and lightweight design make it suitable for integration into various RC models without adding significant weight or bulk.
This is a Radiomaster RP1 ExpressLRS Nano Receiver.
The RP1 and RP2 2.4GHz ELRS nano series receivers are open-source receivers based on ExpressLRS.
The Nano receivers, first developed by Jye Smith from the ExpressLRS development team, feature ESP8285 MCU and SX1280 RF chips. The RP1 has a UFL antenna socket for full-range antenna use. The RP2 has a built-in ceramic antenna which is super light and small in size and ideal for racing.
The RP1 and RP2 feature WIFI built in so you can upgrade firmware by WIFI and configure the Receiver via the built-in WebUI with your PC or mobile phone.
Due to the low-latency and high-refresh-rate RF module, the RP1 and RP2 are ideal for FPV races or Long Range. Suitable for Whoops, drones, and fixed-wing models due to the ultra-light and Nano size, these receivers can fit just about anywhere.
Features:
ExpressLRS Technology: The RP1 receiver is built on ExpressLRS technology, an open-source wireless communication protocol known for its long-range capabilities and low latency. This technology enables extended control distances and responsive communication between the transmitter and receiver.
2.4GHz Frequency: The receiver operates on the 2.4GHz frequency band, which is recognized for its stable and interference-resistant signal transmission. This technology minimizes the risk of signal interference from other radio systems or external sources.
Long Range: ExpressLRS technology provides the RP1 receiver with long-range communication capabilities, making it suitable for long-range FPV (First-Person View) flying and other applications where maintaining a strong connection over a distance is crucial.
Low Latency: The RP1 receiver offers low-latency communication, ensuring quick and precise responses to control inputs from your transmitter. This low latency is especially important for applications that demand immediate feedback.
Compact Design: The receiver is designed to be compact and lightweight, allowing it to be easily installed in various RC models without affecting their performance or maneuverability.
Fail-Safe Function: The RP1 receiver often supports a fail-safe function that can be programmed to return your RC model to a predefined position or perform another predefined action in the event of signal loss. This feature enhances the safety of your RC operations.
Telemetry Support: Some versions of the RP1 receiver may support telemetry, enabling you to receive real-time information about the state of your RC model. This information can include data like battery voltage, signal strength, altitude, GPS coordinates, and more.
Diversity Antenna Setup: The receiver may include a diversity antenna setup with two separate antennas, which continuously monitor the signal strength. The system switches to the antenna with the best reception quality, reducing the risk of signal dropout.
More Features:
- Improved PCB design is better for heat dissipation.
- Upgraded rigid antenna with greater durability and performance.
- LED on the top side of the PCB.
- Solder pads are improved and easier to solder to.
