ESP8266 WiFi Microcontroller – SMT Module
Add the Internet to your next project with a tiny WiFi microcontroller! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While these modules are surface mount, they are very easy to hand solder; we carry a solderless breadboard adapter for this module.
The board has a 4MB flash chip, ESP processor, and onboard antenna. These come pre-programmed with the NodeMCU Lua firmware but keep in mind they will require some extra parts to get going. There is also Arduino IDE support for the ESP8266 if you prefer!
We are now shipping the ESP-12E version which has the SPI flash pads brought out on the bottom row. Note that you cannot use them for GPIOs or anything, they're there so you can program the FLASH chip only.
