Expansion Radio Board

The Expansion Board allows to connect two communication modules at the same time in the Waspmote sensor platform. This means a lot of different combinations are possible using any of the wireless radios available for Waspmote: 802.15.4, ZigBee, DigiMesh, 868 MHz, 900 MHz, LoRa, WiFi, GPRS, NB-IoT / Cat-M, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and RFID/NFC. Besides, the following Industrial Protocols modules are available: RS-485/Modbus and CAN Bus.

Some of the possible combinations are:

  • LoRaWAN - GPRS
  • 802.15.4 - Sigfox
  • 868 MHz - RS-485
  • NB-IoT / Cat-M - WiFi
  • DigiMesh - 4G
  • NB-IoT / Cat-M - RFID/NFC
  • WiFi - 4G
  • CAN Bus - Bluetooth
  • etc.

NB-IoT / Cat-M and 4G modules do not need the Expansion Board to be connected to Waspmote. They can be plugged directly in the socket1.

Applications:

  • Multifrequency Sensor Networks (2.4 GHz – 868/900 MHz)
  • Bluetooth - ZigBee hybrid networks
  • NFC (RFID) applications with LoRaWAN
  • ZigBee - WiFi hybrid networks
