VM21 VIDEO&DATA&RC LINK
Category: Flight controller with FPV system
Model: VM21
VM21 is a digital video transmission device applied in the UAV (Unmanned Aerial Vehicle) field. It adopts MESH networking technology and has multiple advantages. The whole machine weighs 100g (excluding the antenna), and its size is 85mm55mm20mm. The operating frequency covers 800MHz (806 - 826Mhz), 1.4GHz (1427.9 - 1467.9MHz), and 2.4GHz (2401.5 - 2481.5MHz), with 1.4G being the standard configuration at the factory. The external voltage is adaptable to DC 7.4 - 50V (2 - 12S battery), and the operating current is 300mA when powered by 12V. It supports TTL/RS232 transparent serial ports, which are full - duplex and can work at any baud rate. It is also equipped with SBUS 2 and LAN1 signal interfaces. The power range is -40~25dBm, and it is equipped with a 2 - 4dBi rod - shaped antenna. The antenna mode is 1x2MIMO (single - transmit dual - receive). The operating temperature ranges from -20℃ to +65℃, the video delay is less than 300ms, the single - point distance can reach 10km (depending on the environment), the operating bandwidth is 1.4 - 20M, and the power supply interface is XT30. The MESH networking technology enables VM21 to expand the coverage of the UAV network, achieve self - organizing and self - adapting network topologies, improve the reliability and robustness of data transmission, and have good expandability and flexibility.
