WizFi310 Shield

Overview#

This document describes the contents of WizFi310 Shield. WizFi310 Shield is a Shield with built-in WizFi310 WiFi module of WIZnet.

Because WizFi310 Shield is Pin Compatible with Arduino, it can be used in Arduino, and it can be used in Arduino Pin Compatible development platform. It is also used on the WIZWiki Platform.

In addition, an temprature/humidity sensor and an CDS sensor are built in.

H/W Configurations#

DIP Switch Configurations#

SW1 - RXD/TXD Selector DIP Switch#

  • ON : RXD/TXD of WizFi310 connect to USB
    • It is possible to communicate with WizFi310 using USB.
  • OFF : RXD/TXD of WizFi310 connect to J1 and J3
    • UART Pin Header, Arduino PIN
    • If the jumper cap is not attached to the UART pin header, it will not be connected to the arduino pin.
Pin 1 : RXDPin 2 : TXD

SW6 - RTS/CTS Selector DIP Switch#

  • ON : RTS/CTS of WizFi310 connect to D6 and D7
  • OFF : RTS/CTS of WizFi310 not connect to anywhere
  • If the state of SW5 is ON, D6 and D7 of UART jumper can not be used.
Pin 1 : RTS - D6Pin 2 : CTS - D7

SW5 - Aruduino Pin Selector DIP Switch#

  • ON : Connect to Arduino Pin
  • OFF : Not connect to anywhere
Pin 1 : A0 - CDSPin 2 : D14 - DHT11Pin 3 : D9 - WizFi310 Reset Pin

UART Selector Jumper#

  • It can be used when SW2 is OFF.
  • You have to specify the desired Arduino pin, use Jumper Cap to connect J1 to J2, and J3 to J2.
    • Default : J1(RXD) - D1, J3(TXD) - D0
  • If the state of SW5 is ON, D6 and D7 of UART jumper can not be used.
J1 : RXDJ2 : D0 ~ D8J3 : TXD
