Step-Up / Step-Down Spanningsregulator S7V8A

Au lieu de créer un circuit basé sur un régulateur de tension de 3,3 V comme le CI LD1117V33 qui a une sortie maximale de 800 mA, je préfère utiliser les petits régulateurs élévateurs / abaisseurs de Pololu. Il est plus petit et a une sortie maximale de 1 ampère. Excellent produit et à bon prix!

It worked well in my project.

I have used 5 of these in various projects from a desktop fountain to a Li-ion battery tester. So far they work great. Realizing that SMPSs are relatively delicate I am reasonably careful. I have accidentally shorted it out and it survived. I have only lost one due to reverse polarity on the supply leads. It didn't last a moment, but that was my fault.

This little regulator is a must have for micro quad builds using DIY FPV setup. The POT is a bit sensible, make sure to glue it down once you get your desired voltage.

Instead of creating a circuit based on a 3.3v voltage regulator like the LD1117V33 IC that has a max output of 800ma, I prefer to use Pololu's little step-up/step-down regulators. It's smaller and has a 1amp max output. Great product and at great price!
