LILYGO T-A7670E R2 Wireless Module is an ESP32 + 4G LTE Cat.1 wireless development board built for cellular IoT, remote monitoring, telemetry, industrial data transmission, smart terminals, and embedded connectivity projects. It combines an ESP32 MCU with the A7670E-R2 cellular module, giving you a compact platform for projects that need wireless networking beyond Wi-Fi range.
This product includes two Type options: with GPS and without GPS. Both versions are built around the same T-A7670E-R2 module and ship with the core LTE accessories, while the with GPS version adds a dedicated GPS antenna for location-aware applications such as tracking, fleet monitoring, field data collection, and mobile asset reporting.
Important: The SIM card shown in some official images is not included, and the package does not include an 18650 battery.

Why the two variants matter
If your project only needs cellular LTE communication, the without GPS version is the simpler and more economical choice. If you need positioning, route tracking, mobile asset monitoring, or field location data, the with GPS version is the better fit because it includes the GPS antenna in the box.
ESP32 + cellular combination
This board is especially useful because it combines an ESP32 development workflow with a 4G LTE Cat.1 module, giving you a flexible path for building smart connected devices that need cloud access, telemetry, or field deployment.
Deployment note
Before powering the board, prepare the correct accessories for your target use case. Cellular deployment requires the LTE antenna, GPS applications require the GPS antenna, and portable battery use needs a separately prepared 18650 cell.
