4G CAT1 is a specific 4G standard for the IoT and M2M markets, focusing on low power consumption, low cost, and modest data transmission performance while maintaining basic 4G network characteristics. The 4G CAT1 module is designed with energy efficiency in mind, and its power consumption is lower than that of traditional 4G modules in both standby and transmission states. It provides relatively low network latency, which is beneficial for applications with high real-time requirements, such as remote control and instant alarms.
E840-TTL (EC05-xxx) is a small 4G pin module developed by EBITE using 4G CAT1 technology, which has the characteristics of small size, high speed, low latency and simple use, and can realize the networking function of serial port equipment (two-way transparent transmission between serial port equipment and network server) with simple configuration. The product adopts 2.0mm pin header, which is convenient for debugging, and can realize the serial port networking process with simple configuration, which is very convenient to integrate into the Internet of Things project.
E840-TTL(EC05-DNC)、E840-TTL(EC05-DGC)为国内版本，E840-TL(EC05-DNE)为欧洲亚洲版本频段，使用时请注意区分。
