Warnings:
1.This module requires a 3.3V supply for VCC, and 3.3V logic.
2.It is not 5V tolerant, Connect RX or TX on 5V FOR Arduino will destroy this module.
3.You must use a logic level converter, or a 3.3V FOR Arduino
4.The 3.3V supply on Arduino Uno has inadequate current capability to power this module.
5.You must provide a separate, higher 3.3V supply (about 300mA or better)
