Overview

TIDA-00485 uses our SimpleLink Wi-Fi CC3200 Internet-on-a-chip wireless MCU module to create a data bridge between an RS-485 network and a Wi-Fi® network. The SN65HVD72 transceiver provides the RS-485 interface with 12 kV of ESD protection and additional protection is provided on board. The design can be powered with AC or DC power up to 30-V RMS or 48-V peak.

A version of this design with an isolated RS-485 interface is available in TIDA-00486.

Features
  • Add Wi-Fi connectivity to an RS-485 network quickly and simply
  • CC3200 application processor provides adaptability to customer communication protocol
  • Wide-input voltage range of 18-V to 30-V AC and 12-V to 48-V DC
