Powering Arduino board and NeoPixel strip with same power su
Wondering if I can power both my Arduino Mega 2560 and 2 60-LED strips of NeoPixels, from my 5V 10A power supply?
120LED * 60mA each = 7.2A MAX if all pixels are white. That leaves 2.8A for the Mega. Should be plenty, right?!
If it IS possible, and ok to do, then where could I hook up the 5V (from the power supply) to the Mega? "Guessing" plugging it into one of the +5V header pins wouldn't be a good idea, 'cuz there's no protection (for power surges or anything else) behind those pins.... (right?). If so, then would it be best to solder a barrel connector (name?) to the wires, and plug that into the DC Jack on the Mega?
Thanks for the thoughts & help!
