## Description

## Overview

The LILYGO T-SIM7600 combines an ESP32 microcontroller with a SIM7600 series LTE Cat-4 modem delivering up to 150 Mbps download and 50 Mbps upload speeds, making it significantly faster than earlier SIM7600X variants. The board features an 18650 battery holder with an integrated solar charging interface for off-grid deployments, dual USB-C ports (one for programming, one for the modem's network interface), and built-in GPS. Regional variants include the SIM7600E-H (Europe), SIM7600G-H (global), and SIM7600SA-H (South America/Australia), with optional audio decoding modules. Minimum sleep current is just 300µA for battery-powered applications.
