Ebyte E840-TTL (EC05-DNE) LTE CAT1 4G Module, Support TCP/UDP/MQTT/HTTP Protocol
E840-TTL (EC05-DNE) is a small 4G TTL pin module developed by Chengdu Ebyte Electronic Technology Co., Ltd. using 4G CAT technology for the Asia-Pacific region, Australia, New Zealand and other regions. It has small size and high speed. , low latency, easy t use, simple configuration can realize the serial device networking function ( two-way transparent transmission between the serial device and the network server ).
The product adopts 2.0mm pin header, which is easy to debug. Simple configuration can realize the serial port networking process, which is very convenient to integrate into the Internet of Things project. The module supports two sockets, the MQTT protocol, and supports access to the Alibaba Cloud, OneNet, Baidu Cloud and Huawei Cloud Platform, makingit easytoimplement IoT applications.
