## Questions & Answers

**Q: are the pins spaced correctly for thru hole pcb?  thanks**
A: If you mean the standard 2.54mm distance between holes: Yes they are.

**Q: Is input 110-220vac for the 3vdc output version?**
A: All these modules have an input voltage between 90-264V.

**Q: What method do you use to affix a wire to the pins? Seems scary to use the 24g broadboard style jumper wire on them for 120v AC**
A: Those wires work fine. Not enough current going through it to need anything bigger

## Customer Reviews

### ⭐⭐⭐⭐⭐ Handy for small microcontroller projects
*by R***Y on April 21, 2025*

I was taking apart 5v power adapters when I needed a 120v to 5v power source for my small projects. This saves some time, is much cleaner, circuit-board mountable, and only costs a little more. The data sheet suggests a putting protective filtering components on the 120v side of the supply.

### ⭐⭐⭐⭐⭐ Tiny and functioning well
*by S***N on April 27, 2025*

Bought less than a month and tried one with a laser diode works out pretty well so far. Will see how long it goes. Based on the light condition, it’s pretty steady means the output voltage is steady as well.

### ⭐⭐⭐⭐⭐ Great supplies
*by J***. on March 4, 2025*

Great supplies, compact, work well
