WiFi Module - ESP8266 (4 MB Flash)
ESP8266 WiFi Module: program, then connect
This WiFi module, designed as a self-contained system-on-chip, includes a TCP/IP protocol stack, 4 MB memory and a host of additional hardware (regulators, amplifiers, etc.). It will enable any microcontroller, including an Arduino board, to access your WiFi network as part of a connected project.
Its small size in no way compromises its development possibilities thanks to its GPIO ports. A word of caution, you’ll need to install a logic level converter for use with a 5V microcontroller.
