Product information "RS-485 / Modbus Module for libelium Plug & Sense"

The RS-485 / Modbus module has been tested with various devices and is compatible with the majority of commercial modules, but this does not ensure the working with all of them. Be sure that the RS-485 module fits your technical requirements. The final user is the responsable to perform the task of communicatiing the RS-485 module with other commercial devices.

This list includes some of the most common uses of the standard:

  •  Industrial equipment
  • Machine to Machine (M2M) communications
  • Industrial Control Systems, including the most common versions of Modbus and Profibus
  • Programmable logic controllers
  • RS-485 is also used in building automation
  • Interconnect security control panels and devices

 

Electrical Characteristics 

  • Board power voltages: 3.3 V
  • Maximum admitted voltage: -0.3 V to +4 V
  • Max data rate: 2.5 Mbps
  • Temperature range: [-40 °C, 85 °C]
  • Dimensions: 33 x 31.5 mm

Connection Diagram

The RS-485 module uses the SPI pins for communication. The SPI port allows more speed communication and frees up the Waspmote’s UART for other purposes. 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 radios available for Waspmote (802.15.4, ZigBee, DigiMesh, 868 MHz, 900 MHz, WiFi, GPRS, GPRS+GPS, 3G, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and RFID/NFC.) and the RS-485 module. The RS-485 module must be plugged on the socket 0 and cannot be in use with other SPI modules like LoRa or CAN Bus
