SIM7070G NB-IoT / Cat-M / GPRS HAT for Raspberry Pi, global band support, with GNSS positioning

Low power narrow band cellular IoT communication module for Raspberry Pi

Based on SIM7070G, Global Band Support

This is a telecommunication HAT for Raspberry Pi which supports global bands of NB-IoT, Cat-M, and GPRS, as well as GNSS positioning function. Due to its advantages like small size, low delay, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, e-health, and so on.

Compared to SIM7080G, this module also supports GPRS (2G); compared to SIM7000C/E, it is more generic due to the global bands support.
