The Sparkfun Electronics Photon Redboard is a Wi/Fi enabled, 120MHz ARM Cortex M3 powered monster in an Arduino Uno R3 footprint. It has some of the familiar Uno I/O pins, but only 8 digital I/O. There is one DAC output. It runs off of USB or a 6V to 15V wall wart. It is a 3.3V device, so all shields must be 3.3V compatible, and not connect to D8 and D9. The Wi/Fi is capable of up to 65Mbps and has WEP, WAPI, WPA and WPA2-PSK WiFi security modes.
With 1MB flash and 128kB RAM, it is a very useful base for an IoT device.
