The module is based on MP2315, 3A 500kHz synchronous step-down converter.In order to get a fixed voltage operation, you need to depopulate variable resistor and short a corresponding to the voltage jumper.I have two modules tested. Module 1: 3.315V @ open circuit, 3.308V @ 130mA load. Module 2: 3.289V @ open circuit, 3.28V @ 130mA load. Ripple for 3.3V regulation: ~80mVpp @ open circuit, ~40mVpp @ @ 130mA load.
