Feature

●E840-TTL-NB03 is designed for devices with serial interface and network server to transfer data over the network. It supports the B8 frequency band. It can be easily set up with simple AT commands. It can be used to realize bi-directional data transfer from serial to network.
●E840-TTL-NB03 is a NB data transfer module developed by Ebyte. The software is fully functional and covers the most common application scenarios. Users can realize bi-directional data transparency from the serial interface to the network server by simple setup transmission.
●It meets almost all requirements for M2M applications. Supports the transparent transmission of data, supports the TCP / UDP network protocol and the Heartbeat package and registration package function can be customized
●Serial port caching is supported. Serial interface data can be stored locally before connecting the server. The maximum downlink rate of NB data is 85.6 kbps and the maximum uplink rate is 85.6 kbps
●Supports protocols such as TCP / UDP, coding formats CS-1, CS-2, CS-3 and CS-4

[Introduction]E840-TTL-NB03 is designed for devices with serial interface and network server to transfer data over the network. It supports the B8 frequency band. It can be easily set up with simple AT commands. It can be used to realize bi-directional data transmission from serial to network.

The module uses 2.0mm headers to facilitate integration of customer devices using a power supply from 5V to 20V. Support mobile NB card, communication and LED display with compatible level. By default, 3.3V can be applied to 5V level. The interference ability can be used in some environments with strong electromagnetic interference, e.g. in the energy industry.

Features:
It meets almost all requirements for M2M applications.
Supports data transfer, supports TCP / UDP network protocol and Heartbeat package and registration package function can be customized.
