## 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
