====== Bay Area Bridge Kard - Dual H-Bridge Drive Kard ======

Inspired by the Golden Gate and the Bay Bridge in the San Francisco Harbor the Bay Area Bridge Kard maps two independent BD62222HFP-TR H-Bridge circuits on a single Quick Kard.  The BD62222HFP-TR are rated for 30V 2.5A.  But long term use at this high power could heat things up a bit!!!
