10Pcs Mini DC Adjustable Power Supply Buck Module Step Down Module
A part of the review has been auto-translated.
So tiny, but so useful! I needed to add a heat sink to it for my application (20v -> 6v, 600-700 ma), but it's exactly what I needed for my project... Looking forward to finding more uses for it...
really tiny. haven't tested them yet
Amazingly tiny units. I am just testing their capability, but they are well made and look like doing the job of providing low voltage to my projects without requiring much space at all. It was an easy job to solder four pin headers to fit the module on a standard Wish board. I can’t believe the price! ...So I have ordered more already! Thanks Banggood, great deal.
good quality, this is now the second time i bought these modules
Маленький понижающий преобразователь для питания разнообразной электроники от мощного аккумулятора.
easy to use and because it is so small - I use it in my model train to reduce the brideness of lightning and for other purposes.
beautiful
j'en utilise assez souvent sans aucun problèmes de fonctionnement je conseille toutefois de ne pas aller à plus de 500 mA de courant de sortie. Exemple de bidouille pour un éclairage latéral double pour le microscope G600 2 de ces régulateurs plus deux modules pwm pour la variation d'intensité (2 leds de 3W en éclairage)
This product works well. It is tiny, the size of a nail. It is able to output a fixed output voltage regardless of the input value (which must be higher or equal). The chip heats a little (40 or 50°C) depending on the output current, but it is less than a conventional regulator. there is a slight rejection of the cutting frequency (40mv to 340khz) at the exit. It is nevertheless excellent for the price and very convenient
Thank you, 🌟🌟🌟🌟🌟
