The FrSky D4R-II 4-Channel Receiver with Data Port CPPM RSSI 2-Way Telemetry is lighter in weight and smaller in dimension. It has an external analog telemetry port and a digital data-stream port (connect to FrSky Sensor Hub FSH-01). For RSSI (PWM) and CPPM output, if CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8, and CH2 will output RSSI (PWM). What&acute;s more, the FrSky D4R-II receiver is equipped with alarm warning on low voltage, poor reception and more.<!--Features --><p>FEATURES</p><ul><li> Lighter in weight, smaller in dimension</li><li> An external analog telemetry port and a digital data-stream port (connect to FrSky Sensor Hub FSH-01)</li><li> RSSI (PWM) and CPPM output, if CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8,and CH2 will output RSSI (PWM)</li><li> Firmware upgradeable</li><li> Alarm warning on low voltage, poor reception, etc.</li><li> Stable performance, high reliability </li></ul><!--Specifications --><p>Specifications</p><table width="100%" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td width="131"> Brand</td><td width="365"> Frksy</td></tr><tr><td width="131"> Model</td><td width="365"> D4R-II</td></tr><tr><td width="131"> Operating Range</td><td width="365"> Full Range (>1.5km)</td></tr><tr><td width="131"> Operating Voltage Range</td><td width="365"> 3.5-10V</td></tr><tr><td width="131"> Operating Current</td><td width="365"> 60mA</td></tr><tr><td width="131"> Number of Channels</td><td width="365"> 4</td></tr><tr><td width="131"> Compatible FrSky Two-way Telemetry Modules</td><td width="365"> DFT, DJT, DHT, DHT-U</td></tr><tr><td width="131"> Dimensions</td><td width="365"> (1.57 x 0.91 x 0.24)" / (4 x 2.3 x 0.6)cm (L x W x H)</td></tr><tr><td width="131"> Weight</td><td width="365"> 0.18oz / 5g </td></tr></tbody> </table><!--Package Includes --><p>Package Includes</p><ul><li>1 x FrSky D4R-II Receiver</li></ul><!--Extra Info --><!--produts_compatibility -->
