S/W Release of WizFi Shield for Arduino – WIzFi210

Introduction

WizFi shield uses Wiz820io, WizFi210 module and supports the Ethernet and Wi-Fi connectivity simultaneously.

1. Hardware

a)    Ethernet

-. Wiz820io is connected with SPI signals.

-. Other signals

• /SS_WIZ (Input): SPI slave chip select signal
• /RESET_WIZ (Input): H/W reset signal
• PWDN (Input): Set power down mode
• /INT_WIZ (Output): Interrupt signal

b)   Wi-Fi

-. WizFi210 module is connected with SPI signals

-. Other signals

• /SS_WIFI(Input): SPI slave chip select signal
• FAC_RST (Input): Factory reset
• GPIO19 (Output): If this signal is high, indicate the data in the receive buffer in the WizFi210
• WIFI_RST (Input): Reset signal

c)    Hardware description

• a: WizFi210 Factory Reset button
• b: Power LED
• c: Reset button
• d: Power LED of WizFi210
• e: Pin header: Select RUN mode or F/W update mode of WizFi210
• f: Pin header: UART Interface of WizFi210
• g: LEDs: Indicate the operation of WizFi210
• h: Antenna

2.    How to test?

a)    Test environments

. WizFi Shield gets the IP address using DHCP and works as TCP server.

-. Laptop connects to it. After the connection is established, the data between the laptop and WizFi shield is transparent.
