THIS DC-DC Boost Converter Module Board SEEMS FAULTY. IT JUST JUST PASS THE SAME CURRENT WITH NO BOOSTING. I TESTED IT WITH A NEW AA ALKALINE BATTERY. 1.5V ALWAYS DELIVERED, NO BOOSTING. I WOULD LIKE A REFUND FOR THIS ITEM PLEASE.

Tiny little booster for different projects. If you own different voltage boosters, that look exactly the same, there is small regulator on the other side and the last numbers on the chip should be 33 for 3.3V, and 50 for 5V. There isn't any other indicator for the output voltage.
