Main Features:<br />A XROCK Radio V1 ( comprises of an air module and a ground module ) is a wireless communication module designed for real time data exchange between open source autopilot ( such as APM， PX4， PIXHAWK ) and ground station. <br />As it has features of small volume， low power consumption， high data rate， stable performance， strong anti-interference ability and far communication distance， it can bring users more involved flight experience.<br />The air module is the telemetry while ground module is the receiver when the radio telemetry sends vehicle's status information.<br />The air module receives it from the autopilot， modulates and transmits it to ground module wirelessly. Ground module demodulates it and sends signals to ground station monitor to display by way of Bluetooth or USB cable.<br />Download and install Mission Planner or DroidPlanner ground station applications to your mobile devices ( mobile phones， tables and laptops ) when first to use. Ground module can connect to mobile devices by way of Bluetooth or USB cable. The ground station monitor can display vehicle's status information in real time when air module connects to autopilot and ground module connects to the ground station.<br /><br />Specifications: ( Performance Parameters )<br />Type: XROCK Bluetooth Radio V1 - 11<br />Communication Distance: Less than 800m<br />Bluetooth Available Distance: 8 - 15m<br />Working Voltage: 915MHz<br />Maximum Transmitted Power: 100mW<br /><br />Package content: 1 x 100mW Transmitter， 1 x 915MHz Receiver， 2 x Antenna， 2 x Connecting Cable， 4 x Double-side Adhesive<br /><br /><br />    Specifications<br />General<br />  Type: Transmitter Receiver Set                                                 <br />Dimension and Weight<br />  Package weight: 0.200 kg                                                  <br />                        Package size (L x W x H): 24.500 x 9.500 x 3.000 cm / 9.646 x 3.740 x 1.181 inches                                                 <br />Package Contents<br />  Package Contents: 1 x 100mW Transmitter， 1 x 915MHz Receiver， 2 x Antenna， 2 x Connecting Cable， 4 x Double-side Adhesive                                                 <br /><br /><br /><br />                                            <br /><br /><br /><br /><br /><br /><br />                       <br />Product Safety Disclaimer: We do not accept any responsibility or liability for misuse of this or any other product.
