the item came *incredibly* well packed for its size (and it's price, actually) 4x XC6206 breakboard with a capacitor between Vin and GND and another between Vout and GND. Pretty simple, yet neat and ready-made: actually useful to power from USB tiny appliance expecting 2x 1.5V batteries :) Thumbs up for the seller!
Excellent 3V supply! Very very tiny size.
