[Introduction]：E90-DTU (230SL37) is a data transceiver with military-grade LoRa modulation technology. With multiple transmission modes, it works in the (230.125MHz~236.125MHz) frequency band (default 230.125MHz). The transceiver provides transparent RS232/RS485 interface and supports 10～36V voltage input.
