The schematic for the DFPlayer Pro [SKU DFR0768] calls out a 25 pin connector "U1" which physically resembles a USB connector on the actual board.

(1) What interface is that connector? USB? But USB 2.0 Type A/B are 4 pin, Type C is 24 pin, Mini/Micro A/B are all 5 pin. IEEE 1284?

(2) What cable do I need to load audio files to U4 flash memory? A DB25 adapter cable?
