Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! 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. We do sell these on a breakout, but maybe you wanna just put this in your own project PCB. 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.
These modules are very easy to hand solder, with big pads! Adafruit Eagle library (ESP12) without the extra unused pads.
Comes with 4MB flash chip, ESP processor, and onboard antenna. These come pre-progammed with the NodeMCU Lua firmware, so you are ready to work.
For advanced users only! This product is just the module - which can be difficult to use. Click here if you're looking for the Huzzah ESP8266 Breakout!
