[Введение]：E90-DTU(433L30)E-V8 это беспроводной шлюз (радиопередача данных через интерфейс Ethernet), который поддерживает скорость 10M/100M и разработан компанией Chengdu Ebyte на основе технологии связи LoRa и протокола Ethernet. Поддерживает двусторонний сокет, обеспечивает шесть режимов работы: TCP-сервер, TCP-клиент, UDP-сервер, UDP-клиент, HTTP-клиент, MQTT-клиент, а также поддерживает шестисторонние клиентские соединения в режиме TCP-сервера.

【Note】
1. When using multiple groups of digital transmission radio stations for simultaneous one-to-one communication in the same area, it is recommended that each group of digital transmission radio stations set a channel spacing of more than 2MHz;
2. The lower the transmission power, the closer the transmission distance, but the operating current will not decrease proportionally. It is recommended to use the maximum transmission power;
3. The power adjustment function cannot accurately feedback the actual transmit power of "medium", "low" and "extremely low". The values in the table are for reference only and other powers can be customized;
