## Questions & Answers

**Q: Does this have a fly back diode built in?**
A: Yes.

**Q: does this work from the 3.3v output voltage available from a raspberry pi and do I need a series resistor.  is a circuit diagram available.  Thanks**
A: Yes, I have this hooked up to a raspberry pi zero W2 (only using 2 channels) and it seems to be working fine. I can't vouch for long-term use or if its slowly burning anything out. Doesnt seem to pull too much current from the GPIOs when I fire on two simultaneously either
