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
WIZ820io Interface
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

2. How to test?
a) Test environments
Test environment
. 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.
