The Ecuador international joined Wolves in January and was a regular on Nuno Espirito Santo’s bench as the season concluded in the summer.
Campana, formerly of Barcelona SC, is yet to make his debut in old gold and now joins FC Famalicao in a bid to aid his development.
The Portuguese top tier began on Friday and FC Famalicao face Belenenses next on Monday.
All at Wolves wish Leonardo the best of luck during his time in Portugal.
