I was poking around a new device and the power supply was supplying 6.18 volts to a board that appears to have 5v chips…the labels are rubbed off but one has “5v” written on it.
Then I looked in my box of wall warts and saw I have a 6.2 volt adapter. So I am curious why would an EE use 6.2 rather than 5 volts?
For context, the device is a tabla drum machine. The power supply is a bit janky. It uses line level AC. I would like to just power the board directly with a barrel plug and that seems within my ability.
