Atmel and Arduino teamed up at World Maker Faire to introduce the Wi-Fi shield 101. [Gary] from Atmel gave us the lowdown on this new shield and its components. The shield is a rather spartan affair, carrying only devices of note: an Atmel WINC1500 WiFi module, and an ATECC108 crypto chip.

The WINC1500 is a nifty little WiFi module in its own right. WINC handles IEEE 802.11 b/g/n at up to 72 Mbps. 72Mbps may not sound like much by today’s standards, but it’s plenty fast for most embedded applications. WINC handles all the heavy lifting of the wireless connection. Connectivity is through SPI, UART or I2C, though on the Arduino shield it will be running in SPI mode.

The ATECC108 is a member of Atmel’s “CryptoAuthentication” family. It comes packaged in an 8-pin SOIC, and is compatible with serial I2C EEPROM specifications. Internally the similarities to serial EEPROMs end. The ‘108 has a 256-bit SHA engine in hardware, as well as a Federal Information Processing Standards (FIPS) level random number generator. Atmel sees this chip as being at the core of secure embedded systems. We think it’s pretty darn good, so long as we don’t hear about it at the next DEFCON.

The Wi-Fi shield 101 and associated libraries should be out in January 2015. We can’t wait to see all the new projects (and new ways to blink an LED) the shield will enable.
