Warning

• This module requires a 3.3 volt supply for VCC, and 3.3V logic.


• It is not 5V tolant,Connect RX or TX on 5V Arduino will destroy this module.


• You must use a logic level converter, or a 3.3V Arduino


• The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module.


• You must provide a separate,higher 3.3V supply(about 300mA or better)
