Key matrix, work out either MC or dumb resistor array to output correct volts for each stage? * TBD, needs testing; but if LEDs are possible, this should be the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) if we want C3 and C4 could use larger spacing on the larger board underneath the smaller board. // margins from edges h_margin = thickness*2; v_margin = hole_dist_top*2 + thickness; v_margin = hole_dist_top*2 + thickness; v_margin = hole_dist_top*2; output_column = width_mm - thickness*2; // How much to cut off to create a pull request.
