Модули выглядят изготовленными очень качественно. А также они очень компактные. Для сравнения я положил стандартную зубочистку рядом. Схема построена на DC/DC преобразователе "ME2108A" производства "Nanjing Micro One Electronics Inc." Дополнительная цифровая маркировка соответствует выходному напряжению 3.3V, так что описание технических характеристик модулей правильное. Конечно, у меня уже есть планы, где их использовать, и при первой возможности я займусь этим :) The modules look made very high quality. Also they are very compact. For comparison, I put a standard toothpick next to it. The circuit is built on a "ME2108A" DC/DC Step up Converter manufactured by "Nanjing Micro One Electronics Inc." The additional digit marking corresponds to an output voltage of 3.3V, so the description of the technical characteristics of these modules is correct. Of course, I already have plans where to use them, and as soon as possible I will do it :)

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.

these will run a 10watt LED from a single 18650 cell... awesome little things !

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.
