For a project I am working on space matters a lot. So I took the USB connector off my UNO and use 2.54 pins to connect a usb cable on the underside of the UNO, which works a charm.
I found a way of feeding the arduino through the 12V line connected through the Vin port, was wondering if I could leave the 5V and GND in the USB unconnected and only using the D+ and D- lines whilst being able to connect to to the serial monitor? If I leave the 5V and GND lines out the computer won't see the connection.
I tried doing it but I can't get it to work, it would save me a lot of wiring. To my understanding connecting both to vin and the USB at the same time is not recommended.
Any help or suggestions would be appreciated, even a simple "this will never happen" would save me time
