Must have

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.

Great product and at great price!

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!

Small size

These are great regulators for small projects. I use them as an alternative to the arduino power supply to power my project on a wide range of batteries.

Great product

I use these all the time. Reliable and great for fluctuating voltage supply. Nice to have the shutdown pin.

Works Great!

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.
