Ebyte E90-DTU(400SL30P) 10km RS232/RS485 SX1268 30dBM 433MHz Wireless Lora Modem
E90-DTU (400SL22P) is a true high-quality industrial-grade wireless digital radio. The power supplysupports3-level protection, RS485 and RS232 support 4-level protection, and the RF port supports 4-level ESDprotection. It canbe used in industrial applications where the electromagnetic environment is more complicated. The radio adopts LORAspread spectrum technology, and its powerful anti-interference ability makes wireless communication more stableandreliable in the industrial field.
