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