E90-DTU(900SL30)

[Frequency] : 850.125~930.125MHz

[Power] : 30dBm

[Distance] : 10km

[Interface] : RS232/RS485

[Introduction] : E90-DTU (900SL30) is a data transceiver with military-grade LoRa modulation technology. With multiple transmission modes, it works in the (850.125~930.125MHz) frequency band (Default 868.125MHz). The transceiver provides transparent RS232/RS485 interface and supports 8~. 28V voltage input.
