VCC of the module must be connected to a supply in the range of 1.9 to 3.6V. Connecting the module to the Arduino’s 5V supply will damage it. The module has 5V tolerant DIO and therefore it is safe to directly interface it to an Arduino board’s 5V DIO. Please also be aware that in the past we have seen cases where the modules peak transmit power is in excess of what the 3.3V supply on an Arduino board is capable of supplying. We therefore suggest that when powering the module directly from an Arduino board that you attach a 10uF or greater capacitor across the modules VCC and GND pins.
