Thank you Jason for your hard work on this firmware! The per board hash frequency setting is just what the doctor ordered for a couple of my z9 minis! Now for the story.... I was a disbeliever back in the hay day when bitcoin was young, never got into it then (regrets). Years later I have a successful job and can afford an expensive hobby. Plus how else can I support my wife's shopping sprees! Lol. Thanks again for the great firmware!
