Datasheet

The left-most pins are used for power
Vin - power in. This is regulated down to 3.3V so you can use 3.3-6VDC in. Make sure it can supply 150mA since
the peak radio currents can be kinda high
GND - ground for logic and power
EN - connected to the enable pin of the regulator. Pulled high to Vin by default, pull low to completely cut power
to the radio.
