Are there any negative effects of under powering the Arduino 101 or Uno? let's say powering it on AA(1.5V) battery.
In that sense is it safe to power the Arduino 101 with a 9V battery?
I have only used the USB, Enlighten me if I'm off here.
The barrel connector supports 7 V to 17 V and I have tested this on my board. The amount of power required depends on the sketch code. For example, a blank sketch consumes 93 mA at 7 V; the ButtonLED example consumes 78 mA.
Please clear me up if I am wrong, the arduino says "The board operating voltage and I/O is 3.3V but all pins are protected against 5V overvoltage."
Does this mean that I should only give it 3.3V? And the max it can handle is 8.3v? or can it handle 17v?
The I/O pins are 5 V tolerant, but are level shifted to 3.3 V before going into the Curie device. Do not apply more than 5 V to the I/O pins. The Curie device itself is powered at 3.3 V and this is what they mean by operating voltage.
My initial response referred to the DC jack that provides power to the entire board and accepts 7 V to 17 V.
Cool, Thanks.
