SIMCom A7672 4G LTE GNSS Raspberry Pi HAT

Description

The Wittelb SIMCom A7672S 4G LTE GNSS Raspberry Pi HAT is an advanced cellular expansion board engineered for Raspberry Pi-based IoT, telemetry, and industrial monitoring. Leveraging the SIMCom A7672S LTE Cat-1 module, it delivers reliable 4G data and SMS communication, alongside integrated GNSS positioning and cellular-based Location Based Services (LBS) for continuous tracking, even in challenging signal environments. Its compact design and comprehensive features make it an ideal choice for embedded systems requiring robust wireless connectivity.

This HAT offers exceptional flexibility with support for both physical SIM and eSIM, allowing for seamless network redundancy and enhanced deployment options. An onboard Real-Time Clock (RTC) with battery backup maintains accurate timestamps, crucial for secure data logging and time-sensitive applications. Communication with the Raspberry Pi is streamlined via both UART and USB Type-C interfaces, simplifying integration into diverse development workflows.

Designed for industrial reliability, the Wittelb HAT includes dedicated Raspberry Pi GPIO control for critical functions such as power management, module reset, and SIM card switching. This ensures full software-level control over the cellular module, optimizing power consumption and enabling dynamic configuration. Its robust operating temperature range further extends its applicability to demanding environments.
