Raspberry Pi Pinout

Raspberry Pi NB-IoT Shield

It is a narrow band IoT (Nb-IoT) shield for Raspberry Pi. NB-IOT is very suitable for IoT applications with low power consumption. Shield also has the built-in 3-axis accelerometer, temperature, humidity, light sensors, opto-coupler, and relay. If you like, you can also add your own sensors using the built-in 4 channel ADC.

Also using the USB connector you can use the shield with Linux, Windows and Android.


  • LTE BC95 Nb-IoT Module B20 800MHz
  • ADS1015 12 Bit 4 Channel ADC
  • Relay with opto-coupler protection (24V DC, 120-220V AC Switching)
  • Opto-coupler (3-12 V DC switching)- Built-in 3 axis accelerometer (MMA8452Q)
  • Built-In HDC1080 temperature sensor (-40 +125 C)
  • Built-In HDC1080 humidity sensor (0 100%)
  • Built-In ALS-PT19 ambient light sensor()
  • 1-Wire interface (3 male pins)(It can be used with DS18B20, DHT21 etc.)
