Notes
USB Type-B to DC Barrel 5.5/2.1mm: USB provides power delivery through its own standard (USB PD). Connecting USB to a different power connector type is not safe without a purpose-built power supply with the correct output. The USB Type-B (USB) and DC Barrel 5.5/2.1mm (Power) are from different connector families.
