Product Overview
A 4G communication HAT built on the SIMCom A7670E module. It connects Raspberry Pi projects to mobile networks for internet data, SMS and voice calls, and adds GNSS positioning — without depending on Wi-Fi or wired networking.
Typical uses include IoT gateways, remote monitoring, vehicle tracking, smart agriculture and industrial automation.
