SKU: DFR0088
The DFRobot IO Expansion Shield V6, evolving from V5, combines Xbee shield and IO expansion (V4) with SD card support for Arduino. It retains RS485, APC220, Bluetooth, and servo control. V6 adds colored pins (prevent reverse/incorrect insertion), full Arduino R3 support, auto half-duplex RS485, RS485 termination switch, URM04 interface, and serial switch (XBee/RS485/Download) to avoid conflicts. Compatible with Arduino UNO, Duemilanov, Mega 1280/2560.

1. Example Code for Arduino-RS485 Communication
This project demonstrates how to use the DFR0088 IO expansion shield to transmit and receive data via RS485 communication with Arduino. Users can learn how to control the RS485 enable pin for transmission and reception, and how to handle serial data communication.
