For hardware the Guide says to put manufacturer in the name. If a manufacturer is not known, you then cannot put one. Unbranded is not a manufacturer, so it should not be present. You can put what is known:
memory card (in lower case because we do not know what it is called, but we do know what it is)
At the very least.
But I am thinking that if this DC01-A is only visible on the PCB, and no other numbers are visible without taking the item apart, then the title should be something like this:
memory card (DC01-A PCB)
or
memory card (white / DC01-A PCB)
