    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

    SEEMS FAULTY

    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.
