BCST 2230 Lecture 2: ESP8266_WiFi_Module_Quick_Start_Guide_v_1.0.4
Document Summary
Your esp8266 is an impressive, low cost wifi module suitable for adding wifi functionality to an existing microcontroller project via a uart serial connection. The module can even be reprogrammed to act as a standalone wifi connected device just add power! This guide is designed to help you get started with your new wifi module so let"s start! The hardware connections required to connect to the esp8266 module are fairly straight-forward but there are a couple of important items to note related to power: The esp8266 requires 3. 3v power do not power it with 5 volts! The esp8266 needs to communicate via serial at 3. 3v and does not have 5v tolerant inputs, so you need level conversion to communicate with a 5v microcontroller like most arduinos use. However, if you"re adventurous and have no fear you can possibly get away with ignoring the second requirement. But nobody takes any responsibility for what happens if you do.
