@Ken
I noticed I can apply 5v to power the MDBT42 w/breakout board, but all of the pins are only 3.3v tolerant. I believe the answer is "no issue" but is there any issue if I use a 5v power supply to power the breakout board and a couple 9g servos. Then use pins D14-D18 as the signal pins for the servos.
Sorry for the dumb question. Normally I just use the wifi board where it's all 5v tolerant so I never gave it a thought before. But now I'm second guessing myself with this board. I just want to make sure that having the pins connected to servos that are being powered by 5V wont cause an issue for the board before I go powering things up.
Thanks for your help!
