[Introduction]：E22-400T33E is a new generation of LoRa wireless spread spectrum module designed based on the SX1268 chip solution. It has multiple transmission methods, works in the 410.125-493.125MHz frequency band (default 433.125MHz), LoRa spread spectrum technology, compatible with 3.3V and 5V IO ports Voltage, using MINI PCI-e standard package, with UART/RS485/RS232/USB communication interface options, and communication compatible with E22-T series products, which is convenient for users to develop and use. The module has a longer transmission distance and faster speed; it supports wake-up over the air, wireless configuration, carrier sense, automatic relay, communication key and other functions, supports packet length setting, and can provide customized development services.
