ESP-01 - adapter Module 3.3V & 5V - Compatible adapter For Arduino

ESP-01 adapter Module 3.3V & 5V Compatible For Arduino
ESP-01 adapter Module for the ESP8266 3.3V 5V Compatible For Arduino. The ESP8266 module is only 3.3V compatible as is. This adaptor shifts the TTL levels of the ESP8266 module to 5V of the Arduino. See description Below.

You can alo use a voltage divider to do the same function. See my HC-06 blog for a video on creating a voltage divider that would work with the ESP8266 module.

You may obviously try to use the Arduino with a straight coupling to the ESP8266 but you may get an early boxing day surprise, therefore it is not recommended.
