Can I Read Battery Voltage on AX0 Pin?

[johnnyhassle]

• Pin Description Min/Max
• AX0 to AX7 I/O channels 0 V to 3.3 V, 4 mA source/sink

I want read the voltage on pin AX0 from a AAA battery, 1.5V. My question is: what does 4 mA source/sink mean? Can I use this pin for reading de battery's voltage?

Thanks in advance

Is this still with your Arduino? Can you post a datasheet for the part?

I'm not familiar with the Arduino, but it looks like those are digital IO pins, with 4mA source/sink capability when configured as outputs. They would not be suitable for reading an analog voltage. Does your Arduino have an A/D converter analog input?

This is about the x-IMU, I can use it for reading analog voltage but the amount of amps the x-IMU is providing is not enough. I therefor want to use a battery.

Here's a link to the users x-IMU users manual - part --> Auxiliary ports
