and what is on the other side of the board ?, probably lots of other components ??Found this. What could it be? So many resistors and nothing else?
EDIT: Sorry wrong forum, could someone move this to Electrical Engineering?
Thread moved. I agree with @davenn -- show us the other side of the PCBA.and what is on the other side of the board ?, probably lots of other components ??
OK ... so without any other info .... go with my last commentsI took the pictures myself. I found the board in a high school physics collection, in a drawer with other random boards, probably just to show the students examples of printed circuits. There was no further information and nobody knew who originally put it there.
