The XB Radio PRO wireless data communication module provides best-in-class wireless connectivity for drones or IoT devices. They use the DigiMesh network protocol, have intensive network operations and support for sleep routers, and can also use proprietary point-to-multipoint configurations. These modules support line-of-sight ranges up to 28 miles (with high gain antennas) and data rates up to 200 Kbps, making them ideal for extended-range applications that require increased data throughput. The XB Radio PRO module is easy to use, shares a common hardware serial port, and offers a variety of different protocols so that users can integrate with your drone or device with minimal development time and risk. Double-ended switching:XB Radio PRO has built-in TTL and USB ports, seamless switching between air and ground, and greater flexibility to reduce the cost of use. Integrated RSSI output:XB Radio PRO integrates the signal strength output and can be directly connected to the drone controller, allowing the user to obtain the current signal strength in real time to determine the risk of loss.
