Raspberry Pi NB-IoT Shield

Obsolete Product (Not for new designs). Please check the new Cellular IoT Kit as an alternative LPWAN solution. 

This product is a narrowband IoT (NB-IoT) shield for Raspberry Pi. NB-IoT is very suitable for IoT applications with its low power consumption feature. The shield also has the built-in 3-axis accelerometer, temperature, humidity, light sensors, optocoupler, and relay. It is also possible to add your own sensors using the built-in 4 channel ADC.

LTE Cat NB1(NB-IoT) is a more modern and advanced way of Machine-to-machine communication than legacy GPRS connection. In comparison with GPRS, the NB-IoT connection has extremely low power consumption and is much more efficient. This Narrowband-IoT shield allows you to connect your Raspberry Pi to this new cellular network with the help of Quectel’s BC95 NB-IoT module.

Quectel BC95 is a high-performance LTE NB-IoT module offering a maximum data rate of 21.25Kbps downlink and 15.625kbps uplink. The NB-IoT shield has built-in temperature, humidity, light sensors, 3-axis accelerometer, a relay and more. Built-in SMD antenna lets you establish the connection right out of the package.
