This chapter introduces the description, features and application areas of Cellular IoT App Shield.

This is an add-on for Raspberry Pi that has combined LTE technologies Cat.M1, Cat.NB1 (NB-IoT) and eGPRS for Raspberry Pi, based on Quectel’s BG96 module. The shield has the power of the new IoT phenomenon LPWA (Low Power Wide Area) with Cat.M1 and NB-IoT connection functionalities. Besides, it also provides the function of eGPRS that be enhanced version of classical GPRS.

The module on the shield has GNSS (GPS, GLONASS, etc.) functionality for the need for location, navigation, tracking, mapping and timing applications.

The design has a built-in temperature, humidity, light sensors, 3-axis accelerometer, and relay. If you do not need these built-in features, you should take a look at Raspberry Pi Cellular IoT HAT.


The ancient 2G cellular network is now dying. New and better LTE technologies are being used instead. LTE Cat M1/Cat NB1(NB-IoT) is the latest way of the machine to machine communication. This LTE shield for your Raspberry Pi lets you connect the Raspberry to this new cellular networks thanks to the Quectel BG96 LTE module on it. It also provides the connection to eGPRS that is the enhanced version of classical GPRS.

Quectel BG96 is a series of LTE Cat M1/Cat NB1/EGPRS module offering a maximum data rate of 375Kbps downlink and 375Kbps uplink with worldwide coverage. The shield has built-in temperature, humidity, light sensors, a 3-axis accelerometer, a relay and more. This LTE add-on for Raspberry Pi also supports GNSS(GPS, GLONASS, etc.) for the need of getting location, navigation, tracking, mapping and timing applications.
