Driver Module PCBs

I’ve added another update to my page on my Switch Machine Controller design (version 2). The update adds a “Driver Module printed circuit boards” section which describes PCBs which I’ve had made to support both the low-current (L293D) and high-current (TB6612) versions of my switch machine driver modules.
