I am wondering,
Nano V3.0 has Both 5V and 3.3V pins to provide power to modules or components, but 3.3V is only "ON" or Available, When NANO is powered via USB port.
SO my Question: As long as its regulated 5V input via USB, Does it matter if the D+ D- lines/wires are absent??? As I have USB cable for just powering/charging, but would be perfect. IF so, I can use a USB Power Bank Right , IF this is a possibility????
And Again the reason for wanting to do it this way is 3.3V pin only works when Nano powered via USB.
Thanks For Your Help
As far as I know it should be entirely possible, But I am not an expert or an engineer.
You can indeed use the nano and disregard the usb-datalines. Keep in mind though that the USB-chip, which provides 3.3volts, is still connected to pins 0 and 1 if you do. It's best to avoid using those pins in your project.
Thank You Mr. Simpson,
Pins 0 and 1 ,
Aren't those the tx and rx pins? I wasn't really planning using those pins.
Well, thats great news.
