E70G-EU Arduino HAT Overview
The Arduino LTE HAT is a compact and powerful 4G LTE expansion board designed for Arduino development platforms. Powered by the Eicut E70x series LTE module, this HAT provides stable cellular connectivity for IoT, M2M, remote monitoring, industrial automation, and cloud-based applications — without requiring complex RF design, SIM circuitry, or external power management.
Designed for seamless integration with popular Arduino boards such as Arduino UNO R3/R4, Leonardo, Zero, and Yun Rev2, the board enables fast and reliable LTE communication with support for TCP/IP, MQTT, HTTP/HTTPS, FTP, CoAP, and other industrial communication protocols.
With built-in Nano SIM support, USB Type-C interface, GNSS antenna connector, status LEDs, and extended GPIO access through a 2×9 pin header, the Arduino LTE HAT is an ideal solution for developers building connected devices in environments where Wi-Fi is unavailable or unreliable.
The module can be quickly configured using Quectel QNavigator software via USB connection. Simply connect the board using a USB Type-C cable, install the software, select the correct COM port, set the baud rate to 115200, and start sending AT commands for testing and development.
