This is the improved Quad Stall Motor Controller w/ point Sense "hat" for the  

Raspberry  Pi. It uses  TC4428's to drive the Stall Motors and uses 

SN74AHC00N's wired as RS FlipFlops to debounce the point sense (assumes a SPDT 

switch mechanically connected to the points (or the internal switch in the 

Stall Motor). Uses 8 GPIO pins:
