SIM7000 LTE Shield

Abstract

1. Introduction

This shield uses SIMCOM's SIM7000-series module, a low-power cellular module that supports LTE CAT-M1 and NB-IoT technology and integrated multi-GNSS (GPS, GLONASS and BeiDou/Compass, Galileo, QZSS standards) for location tracking. The shield also includes a high-accuracy I2C temperature sensor for IoT monitoring applications.
