The iten shown has pins attached the item deliverd had no pins either attached or lose. More important is that they do not work, the voltage on the output pin is the same as the voltage on the input pins.

All 10 pcs of the Modules does not work as discribed. The Output V is the same as the Input V. If the V in is 2V the output V is 2V. If the V in is 4V the output V is 4V. Regards wkarg
