ESP8266
IoThursday
The ESP8266 has been discussed quite a bit in the regular IoThursday meetings.
ESP8266
The ESP8266 is a microcontroller that has WiFi built in, making it a great starting device for all things IoT.
Getting Started
A section for useful information on getting started with an ESP8266 module
Modules
A subsection to explain the different modules and what differs between them
NodeMCU v2
An open hardware board (costing about £3.50) that combines the ESP-12-E core (32Mbits(4MBytes) flash) with a CP2102 USB-UART so you can connect it directly to a PC USB with a standard USB micro cable. It comes flashed with a Lua core but that can easily be replaced with an Arduino core with all the Lua core features plus anything vanilla that works with Arduino.

Connecting to an ESP8266 module
What you'll need:
- An ESP8266 module with
- A breadboard and suitable cables
- A USB to TTL Serial adapter
- A computer to connect to the ESP8266 with
