LILYGO TTGO T-A7670G/E/SA R2 is a small, capable board for 4G IoT and embedded projects. It runs on an ESP32 MCU at 240MHz, with 4MB flash and 8MB PSRAM, and includes a CAT1 LTE module for mobile data and SIM support. You get Wi-Fi 802.11 b/g/n and Bluetooth 4.2 for flexible wireless connections, plus a range of interfaces for sensors and peripherals.

This board supports GNSS (BeiDou, GPS, GLONASS) for location tracking, and has a SIM card slot, SD card slot, and USB for easy expansion. It’s designed for low power use, with LTE drawing just 3.8mA and GSM 3.5mA. The board is compact (24 x 24 x 2.3mm) and works from 3.4 to 4.2V, making it easy to fit into portable devices.

You can use it with Arduino, and it supports protocols like TCP/IP, FTP, HTTP, and HTTPS. Security features include TLS and file system support, plus firmware updates over the air. The package includes the T-SIM-A7670 module, LTE antenna, power cable, pins, and (optionally) a GPS antenna.
