  • Where are the pullup resistors for the inputs?? With no pullup resistors, how does the line go back to a logic 1 after you’ve removed the trigger (short to ground)?? Such a great idea but so poorly done. I will definitely be more careful to check schematics before I order anything else.

    I assume this is the cause of random triggers and crosstalk. Unless I’m missing something?

No public wish lists :(
