The Multiprotocol Radio Shield is an interconnection shield for Arduino, and was designed to connect two communication modules at the same time. This that means a lot of possibilities and applications can be made using the cooking-hacks modules. The Multiprotocol Radio Shield includes the SPI bus connections that allows the use of the RS-485, CAN Bus, LoRa modules and LoRaWAN, but also is compatible with the rest of the cooking-hacks modules as RFID, XBee or Bluetooth.
As an example in the pictures below we can see several examples of double radio integration: RS232 + Bluetooth (left), RS485 + RFID (center), Can Bus + 802.15.4 / ZigBee (right).
Let's summarize what we can do using this shield:
- Connect any Arduino Wireless module. Some examples: XBee 802.15.4/XBee ZigBee, RFID, NFC, Bluetooth, Bluetooth Pro, Wifi,GPRS, 3G, LoRa, LoRaWAN.
- Connect the new Industrial Protocol modules as RS-485, RS-232 and CAN Bus.
- Combine two communications protocols (RS-485 with RFID, CAN Bus with Bluetooth, etc).
The Multiprotocol Radio Shield includes two sockets. In these two sockets can be connect any module that uses UART. As for using SPI modules, there are two possibilities. If SPI uses 3V3 voltage levels, you must connect it in the SOCKET1, and if it uses 5V levels, in SOCKET0.
