Ebyte EWD611-900NW20(485) RS485/Ethernet port 850MHz/915MHz 20dBm 1km Long distance image and data transmission radio DTU

EWD611-900NW20(485) Long-range digital transmission + mapping Support star networking Equipped with AT instruction [Interface type]：RS485/network port [Transmitting power]：20dBm [Communication distance]：1km [Size]：66*68*21.6mm [Introduction]：EWD611-900NW20(485) is a long-distance image transmission + data transmission radio developed by Ebit. With a transmission rate of 16Mbps, it can realize 4-channel 1080p video transmission, and can also achieve transparent transmission of network port + serial port at the same time. It works in the 850MHz~930MHz frequency band, and the maximum RF transmission power is 20dBm. The digital radio uses universal AT commands, which is simple and fast to operate. It can be widely used in smart wearables, home automation and other fields.
