Sweet, some great tips! Question - if I short out digital outputs (by accident, of course) would that be equivalent to shorting out the LiPo itself?
If you use the barrel jack (rather than Vin) you get the benefit of the reverse-polarity protection, plus that diode drops 0.7V which takes some of the load off the voltage regulator.
Is it safe to use a 11.1V 1300mAh LiPo Battery designed for RC cars/planes with my new Arduino Nano? I read that the Nano can operate on 6-20V with 7-12V being recommended, so it sounds to me like it would be fine?Also, I know I plug the positive lead into VIN (pin 30) so do I plug the negative lead into GND? It's been a while since I've done any electronics tinkering, please excuse my noobiness.Thanks!
Yes that should be fine. If you are using the Nano to supply lots of current its regulator might get quite hot though -the higher the Vin the more heat. In fact current x (Vin - 5) = heat power to the regulator.Given its a high current battery it would be wise precaution to add say a 1A or 500mA fuse on the wire to Vin if possible.You must be very careful never to short out a LiPo pack, they can source huge currents.
