Internet-enable your microcontroller projects for under $6 with ESP8266 (Opensource.com)

David Egts takesa look at the ESP8266 WiFi chip, on Opensource.com. "What isthe ESP8266 exactly? The ESP8266 is a 32-bit RISC CPU made by Espressif Systems. Its clock runs at80MHz, and it supports up to 16MB of flash RAM for program storage. Thesespecifications are quite impressive when compared to an Arduino UNO, whichruns at 16MHz, only has 32KB of RAM, and is several times moreexpensive. Another big difference is that the ESP8266 requires only 3.3volts of power while most Arduinos require 5 volts. Keep this voltagedifference in mind when extending your existing Arduino knowledge andprojects to the ESP8266 to prevent magic smoke."
