The Happymodel ExpressLRS ES900RX Receiver Module is a high-performance receiver module designed to work with compatible transmitters. It utilizes ExpressLRS technology, which is known for its long-range and low-latency wireless communication capabilities. This module is designed to be a versatile and high-quality solution for RC enthusiasts who require reliable long-range control over their models.
Features:
ExpressLRS Technology: The ES900RX module is built on ExpressLRS, which is an open-source wireless communication protocol known for its long-range capabilities and low latency. This technology enables you to maintain a robust and responsive link between your transmitter and your remote-controlled model.
Long Range: One of the key features of the ES900RX module is its long-range communication capability. It allows for extended control distances, making it suitable for long-range FPV (First-Person View) flying and other applications where maintaining a strong connection over a distance is essential.
Low Latency: ExpressLRS technology provides low-latency communication, ensuring that control inputs from your transmitter result in immediate and precise responses from your model. This low latency is especially important in scenarios that require quick and accurate control.
Compatibility: The ES900RX module is designed to be compatible with various transmitters and flight controllers. It’s crucial to ensure compatibility with your specific equipment before use.
Telemetry Support: Some versions of the ES900RX module support telemetry, allowing you to receive real-time information about the state of your model, such as battery voltage, signal strength, and other relevant data.
Diversity Antenna Setup: A diversity antenna setup is often featured in the module, which includes two separate antennas. This setup continuously monitors both antennas and switches to the one with the best reception quality. This enhances signal reception and minimizes the risk of signal dropout.
Easy Installation: The module is typically designed for straightforward installation, making it user-friendly and accessible for hobbyists and RC enthusiasts.
Fail-Safe Function: The ES900RX module may include a fail-safe function that can be programmed to return your model to a predefined position or perform another predefined action in the event of signal loss. This feature enhances the safety of your RC flights.
Compact Design: The module is usually lightweight and compact, allowing for easy installation in various RC models without adding significant weight or bulk.
