I found this on the ground on the way to one of my customer. Apparently, its some kind of circuit board for controling a system. But, when I have the time, I will clean it up and see what kind of circuit I can do with it. At the moment, I am thinking of connecting them to a battery and when each switch is pressed, the LED will light up. or maybe not.

The circuit board is double-sided with the SMT
LEDs and switch on one side.

And the rest of the tracks on the other side
