    Embedded Systems Test Review

    I am an absolute beginner in Embedded Systems and I had an idea to test the Allwinner A83T processor with an bare bones board test and so I completed the design yesterday. But before I get it made by JLCPCB (because of $8 4 layer fabrication), I need somebody to tell me if this will boot and...
