GCORE VCU

My projects have led me to gain a deeper understanding of electronics - specifically embedded systems. Over the past year, I have been practicing my skills in embedded systems to ultimately make my VCU (vehicle control unit).  I call it the GCore and it is tasked with integrating every electronic node in my current EV project as well as many to come.  There are many mistakes ahead but I am excited about finally wrapping my head around this stuff.
