EC25-E Arduino HAT Development Board Description

The LTE Arduino HAT Development Board is a compact, portable evaluation board specifically designed for easy integration with Arduino ecosystems. It comes pre-equipped with a high-performance LTE Cat 4 wireless communication module (EC25 series), enabling fast 4G connectivity with maximum downlink speeds of up to 150 Mbps and uplink speeds of up to 50 Mbps.

The board features a convenient USB Type-C interface for both power supply and data communication — developers only need a single USB Type-C cable to power the board, configure the module, send AT commands, and transfer data. Thanks to its Arduino-compatible pin headers and layout, the development board can be directly stacked onto standard Arduino shields or used with a wide range of existing Arduino expansion boards without any adapters. This makes rapid prototyping of IoT applications extremely simple and efficient.
