Tired of trying to fix that old pop bumper board? This board should do the trick.
It has been completely redesigned to fix problems with the original board.
It has a green and red LED to indicate trigger in and trigger out.
It has a button to test the board function.
And it has a feature that will prevent damage to the transistor even if the diode is not present on the solenoid! The other folks warn you to double check the diode. With this board, it does not matter. The feature is called Pop-zor-ber.
