NB-IoT (Narrowband Internet of Things) technology is a direct competitor to LoRaWAN and SigFox and has a few advantages:

  • higher speed 25.5 kbps up and down link
  • single GSM cell can connect to up to 100 000 NB-IoT nodes
  • single GSM cell can cover up to 10-100km rural and 1-10km urban distance
  • can work up to 10 years on Lithium 3V battery if less than 200 bytes are sent per day

Note: All GSM cells which work with LTE can also support NB-IoT, but this requires new protocol installation and licensee fee, so not all operators provide it by default. You have to check with your local GSM operator if he offers NB-IoT. Also SIM card must have this protocol enabled. SIM with LTE may or may not work with NB-IoT, this depends on your operator.

NB-IoT-BC66-ANT has GSM antenna included. 
NB-IoT-BC66H has EXT1 and EXT2 headers soldered.

NB-IoT-BC66 modules are meant for embedding. Experience with BC66 technology is required. For research and development it is highly recommended to evaluate the technology with NB-IoT-DevKit first (before switching to the modules)!

Distance between EXT1 and EXT2 = 22.86 mm (0.9" )
Distance between EXT2 and EXT3 = 2.54 mm (0.1")


  • BC-66 all world wide GSM bands coverage
  • NB-IoT 25.5 kbps up and down link
  • Ultra low power design only 126 uA consumption in PSM mode
  • Nano SIM
  • Level shifters for 5 x GPIOs, I2C, SPI, UART
  • U.FL antenna connector (-ANT option)
  • Status LEDs
  • Dimensions: 26 x 26 mm


  • The module stops after some time. Can't access it anymore. What is the problem?
  • By default the module might be set to power saving and might enter sleep. Make sure to disable sleep modes (AT+CPSMS=0 to disable power saving mode setting).
