Just a quick question about connecting a battery to my Nano when I already have a sensor (MS5611 barometric) connected.
My MS5611 sensor is connected to the GND and 5V (27) but instead of running off the USB I want to run it off batteries. either lipo or AA’s
If the sensor is already connected to the 5V, can I also connect my battery positive to this pin as well?
Or possibly use the 3V3 pin (17)?
