The SparkFun LTE CAT M1/NB-IoT Shield with Hologram SIM Card equips your Arduino or Arduino-compatible microcontroller with access to data networks across the globe without needing to provide your own subscriber identity module. This shield adds wireless, high-bandwidth cellular functionality to your IoT project while maintaining low power consumption and a small footprint. The SparkFun LTE CAT M1/NB-IoT Shield is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.
At the heart of the LTE Cat M1/NB-IoT shield is a u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem. Cat M1 (Category M1) and NB-IoT (Narrowband IoT) are both Low Power Wide Area Network (LPWAN) technologies that are designed to provide cellular communication to small IoT devices. They operate on LTE network bands just like most smartphones, and should be supported by most cellular network carriers. The u-blox SARA-R4 module communicates over a UART via a simple AT command set. We've provided a library to help you get started with everything from sending SMS text messages to communicating with servers over a TCP/IP connection. Additionally, both the module and library support an I2C GPS interface via a Qwiic connector, so you can plug in a u-blox GPS module and start remotely tracking your project.
Each SparkFun LTE CAT M1/NB-IoT Shield also includes a ceramic, Molex 1462000001 SMD antenna. The antenna has a gain of 3.8dBi around 1.7GHz to 2.7GHz. However, if you would prefer to use an external antenna, Sparkfun have provided a U.FL connector that can be utilized by simply slicing through a jumper with a hobby knife.
Please be aware that you will need to supply and solder on your own headers before attaching it to your Arduino based device. Also, if you already have your own SIM, Sparkfun also offer this shield without a card included.
Note: Be sure to check the Hardware Overview section in the Hookup Guide for compatible GPS modules. The onboard Qwiic connector is only designed to support u-blox-based GPS modules. It does not support any other GPS modules or sensors. Sparkfun are continuing to add more modules so be sure to check back every so often to find out more!
