[Introduction]:E90-DTU (900SL33) is a wireless data transmission radio using military-grade LoRa modulation technology. It has multiple transmission methods. The default working frequency band is 868.125MHz, and it supports 8-28V voltage input. The module has a software FEC forward error correction algorithm that can actively correct interfered data packets, greatly improving reliability and transmission distance. The radio station has the function of data encryption. The data transmitted by the radio station in the air is random. Through the strict encryption and decryption algorithm, the data interception is meaningless; it supports the setting of sub-packet length, and supports different real-time and data packets.
