## Description

## Overview

The LILYGO T-A7608E-H is a cellular IoT development board based on the ESP32-WROVER-E MCU (4 MB flash, 8 MB PSRAM) paired with the SIMCOM A7608E-H LTE Cat-1 modem. It supports voice calls, SMS, and LTE data over TDD bands B38/B40/B41 and FDD bands B1/B3/B5/B7/B8/B20, with fallback to UMTS/HSPA+ and GSM/GPRS/EDGE on 900/1800 MHz. An integrated GPS/GNSS module with IPEX antenna connector provides positioning capability. The board features a MicroSD card slot, 18650 battery holder, USB-C programming port via CH9102, and exposes standard I2C, SPI, and UART interfaces for peripheral expansion.
