Margin // margins from edges h_margin = hole_dist_side + thickness; width_mm = hp_mm(width); // where to put the notice in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages.
