Product Descriptions

  E840-TTL (4G04-DNC) is an LTE data transmission module product launched by Yibaite. The product has complete software functions and covers the vast majority of conventional application scenarios, E840-TTL (4G04-DNC) is a product developed to achieve data transmission between serial devices and network servers through the network. This product is an LTE-FDD/LTE-TDD/WCDMA/TD-SCDMA/CDMA/GSM wireless communication data transmission module with diversity reception function, supporting LTE-FDD, LTE-TDDDC-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, TD-SCDMA, CDMA, EDGE, and GPRS network data connections allow users to achieve bidirectional transparent data transmission from the serial port to the network server with simple settings.

  The module uses 2.0mm pins for easy integration of customer equipment, and is powered by a wide voltage range of 5V to 18V. Supports 4G cards for mobile, China Unicom, and telecommunications, with compatible levels for communication and LED indication. The default voltage is 3.3V, which can be applied to 5V levels. It has anti-interference ability and can be used in environments with strong electromagnetic interference, such as some power industries. This chapter is a quick introduction to the E840-TTL (4G04-DNC) product, which involves setting up the simplest hardware environment to test the network transmission function of E840-TTL (4G04-DNC), that is, achieving bidirectional data transmission from serial devices (referring to computers) to network servers.
