I’m blocked by a mechanical conflict in the pasted placement map: the left-column bottom hole is D5 at X=0, Y=0, while the bottom-row left hole is RST at the same X=0, Y=0, so two different nets occupy the same drill hole.
Added H1/J2/J3/J4 and wired the schematic netlist.
Set the PCB to 18 × 15 mm, 2 layers, and started through-hole pad geometry.
To continue, I need one clarification: should the bottom row start at X=2.54 mm instead of X=0 so it does not overlap the left column, or is one of the listed corner nets incorrect?
