More information:
This module contains ESP8226 IC for communication over a serial link using simple AT commands.
This module requires a power supply of 3.3 V for VCC and 3.3 V logic. Is not 5V tolerant.
By connecting the RX or TX on 5V Arduino with this module will be destroyed. You need to use a converter of logic levels, or the Arduino at 3.3 V.
Power supply 3.3 V on the Arduino Uno is not sufficient for the power supply of this module. You need to ensure a separate. A convenient source of 3.3 V (300 mA or better)
To the module it is necessary to connect an external antenna. If you are searching for module with integrated antenna, is also in our offer.
