PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces,
it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no
external RF parts.
There is an almost limitless fountain of information available for the ESP8266, all of which has been
provided by amazing community support. In the Documents section below you will find many
resources to aid you in using the ESP8266, even instructions on how to transforming this module into
an IoT (Internet of Things) solution!
Note: The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic
Level Converter. Please do not power it directly from your 5V dev board.
