NB-IoT / Cat-M(eMTC) / GNSS HAT for Raspberry Pi, Globally Applicable

A multi-function telecommunications HAT for Raspberry Pi featuring NB-IoT, Cat-M (eMTC), and GNSS positioning. Based on the SIM7080G module with global band support, it's ideal for IoT applications requiring low-power wide-area connectivity and location tracking.

Supports multiple protocols including TCP, UDP, HTTP, HTTPS, MQTT, CoAP, and LWM2M. The onboard USB port allows direct AT command testing and GPS data access.

Key Features

• NB-IoT & Cat-M – Global band support for low-power IoT connectivity
• GNSS Positioning – GPS, GLONASS, BeiDou, and Galileo support
