Connect your projects to the internet with the WiFi TinyShield! Based on the Atmel ATWINC1500 WiFi module, this module supports 802.11 b/g/n, SSL, different security modes (WEP, WPA, WPA2, and unsecured connections) and has a built-in TCP/IP Stack that offloads network processing from your TinyDuino. The easy to use Arduino/Atmel supplied software library shows numerous examples on how to scan for WiFi access points, connect to an access point, run DHCP, ping IP addresses, do DNS lookups, connect as a client to a webserver and download web pages, or even act as your own webserver and access point.

This TinyShield includes an integrated antenna on the module itself with FCC/CE approval as well as built-in LEDs that indicate connection state and active data transfer. This TinyShield also includes level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V, and uses an SPI interface to allow for fast data transfers.

Note: This module can act as an access point!

Pins Used

SPI Interface used

• A3 - RESET: This signal is an input to the WiFi module and is used to reset the module.
• 8 - SPI_CS: This signal is the SPI chip select for the WiFi module
• 2 - SPI_IRQ: This signal is the interrupt output from the WiFi module and into the TinyDuino.
• 11 - SCLK: This signal is the serial SPI clock out of the TinyDuino and into the WiFi module.
• 12 - MISO: This signal is the serial SPI data out of the WiFi module and into the TinyDuino.
• 13 - MOSI: This signal is the serial SPI data out of the TinyDuino and into the WiFi module.
