    Step-Down Power Adjustable Module With Lm2596s
    ЭПонижающий мощность модуль с Lm2596s.
    Обратите внимание что модуль не имеет защиты от дурака - если подключите неправильно полюса плюс и минус, то основная схема сгорит!

    step down board
    Item looks to be good quality. Soldering is good and size is perfect to fit inside future projects. See my video for a much better look at the parts and the product.

    Step-Down Power Adjustable Module With Lm2596s
    Interesting Step-Down Power Adjustable Module With Lm2596s. Tiny power voltage adjustment module. Good exercise with a multimeter testing the voltage output.
