[Introduction]:E90-DTU (400SL30L) is a wireless data transmission radio using military-grade LoRa modulation technology. It has a variety of transmission methods and works in the (410.125~493.125MHz) frequency band (default 433.125MHz). The radio provides RS485 and TTL two kinds of serial communication Port, support 8~28V DC power supply or 4.2V lithium battery power input, support reverse constant current charging.
