    I mentioned this in another post, but yes, resistor dividers are useful and have been used for ages. However things like component aging/damage and simply having enough headroom between different options limits the number of discrete states you can convey with a resistor divider.

    I’m usually not a fan of overcomplicated solutions, but these identity chips aren’t that.
