Hi, <I guess this is a “part” ;D>
I etched one of those MBHP_BURNER_V1_PLUS boards and couldn’t seem to find a connection while skimming over it:
There’s a large, almost square ground pour near the center of the board, where the Vpp/Vdd lights are. Then, there’s the main pour surrounding most of the board. I couldn’t see any connection between the two. I see a connecting trace which rides up between the legs of the 40-pin socket (pins 8/9 and 32/33) and connects that square part to a pour at the ass end of the add-on 18-pin socket, but nothing to the main pour.
Am I missing something?
Much Thanks,
George
