## Questions & Answers

**Q: This board will able to connect led light and sound?**
A: It can be used the same as any  Arduino, it just has fewer inputs and outputs. It also needs any headers you want to use soldered on.

**Q: Where can I get a schematic for this board?**
A: Sparkfun, https://www.sparkfun.com/products/11113

**Q: 150mA output? 
I see that these have a max output of 150ma- is that total? Digital? Analog?
I am looking to run 27 charlieplexed LEDs in open heart**
A: 150 mA is the limit for the onboard voltage regulator.  The Pro Mini should have no trouble driving 27 Charliplexed LEDs directly because it's only turning on a few LEDs at time.

**Q: Does this board include the 3 pin headers for programming and breadboard mounting?**
A: This board does not include any headers.  Many of our customers already have headers or prefer to choose what they want to put on the board.
