Features 1、Excellent Anti-interference: The rc transmitter with DSSS/u0026FHSS working synchronously to keep the excellent anti-interference performance, only 3ms for 10 channels response. CRSF Protocol Supported: On the basis of the RadioLink unique communication technology of DSSS and FHSS, CRSF protocol from Blacksheep is added. Compatible with TBS Crossfire 915 module. 2、Compatible with SBUS, PPM, PWM and CRSF: With DSSS/u0026FHSS protocol, SBUS, PPM and PWM can operate simultaneously for seamless user control. With CRSF protocol. 3、Real-time Information: When PRM-03 module works with flight controller, model voltage, speed, climb, throttle, longitude, latitude, altitude, GPS, RSSI, flight mode, yaw, roll, pitch and distance are displayed on the LCD screen display. Adapts to Most of Types of Aircraft: Easy to understand user software makes quick work of changing aircraft types, Rotary Wing, Glider, Multicopter, Car, Boat, Robot. 4、USB Based Update: Transmitter is easily updated with the latest firmware by USB cable to connect PC. Voltage conservation System: RadioLink/u0027s voltage conservation software ensures vital components are protected from a reverse polarity connection. 5、Support for Universal Battery: JST 2Pin connector supports multiple type batteries: 8 pcs AA or 2s-4s LiPo battery. (Not included batteries) A 3s 1800mAh liPo battery can work more than 12 hours.
