1 Product Overview

1.1. Introduction

E840-TTL-4G02E is developed for serial port devices and network servers to
transmit data to each other through a network.It is a
LTE-FDD/LTE-TDD/WCDMA/TD-SCDMA/CDMA/GSM wireless communication
data transmission modem with diversity receiving function, supporting LTE-FDD,
LTE-TDD, DC-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, TD-SCDMA, CDMA,
EDGE and GPRS network data connections, through simple AT commands Settings,
you can easily use this product to achieve two-way data transparent transmission from
serial to network.
The module with 2.0 mm pin header is good for embedded development by a wide voltage of 5.0V to 20.0V.
Support 4G card, RS485 and RS232. With circuits electrical isolation scheme for anti-interference ability, it can be used
in environments with strong electromagnetic interference, such as power industry. This manual is a quick introduction to
the modem E840-TTL-4G02E. It is the easiest hardware environment to test the E840-TTL-4G02E network transmission
function, that is, to realize data being transmitted in both directions between the serial device (here, the computer) and the
network server.
