Work temperature Power range. 40? ~+70? -DC 928V Battery 3S6S. M50&M51, designed for drone, is a kind of wireless FHD video and data transmission system. It has the advantages of small size, low power consumption and long distance. The system can transmit FHD video, flight control data, gimbal control data, and RC control data simultaneously. 265 video CODEC and OFDM modulation technology, M50&M51 can achieve low latency, high resolution video transmission. With advanced radio frequency technology, M50&M51 can support three frequency bands. Users can change frequency bands easily. Users can choose the suitable frequency band according to local regulations. The Chinese radio type approval ID is 2019DP8189(CMIIT ID:2019DP8189). Also you can choose frequency hopping or fixed mode under special conditions. The air unit of M50&M51 system can be configured to Point-to-Point mode or Repeater mode. Users only need one more air unit and simple configuration to achieve long distance transmission. Please watch the instruction video for more information. M50&M51 has an encryption function. Users can Enable/Disable this function when needed. It is easy to set encryption code using Maestro Assistant or Web UI. The device has 2 UART-UART1 and UART2. Two protocols, Mavlink and Transparent, are supported. Users can use it for flight control data and gimbal control data transmission. Also the system can improve the RC control distance via the SBUS port. On the ground unit of M50&M51, there is a USB 3.0 port. User can add a USB storage device to save the FHD video. M50&M51 support a variety of video input and output interface, such as HDMI, Ethernet, SDI, CVBS. It can also match most gimbal on the market.
