Today I continued working on the PCB for my Mechanical Calculator project.

After finishing yesterday’s schematics I assigned the footprints to each component of my build.

NOTE: I plan to hand-wire the battery to the microcontroller later when I have the materials ready.

I designed my PCB to be 86mm x 126mm using KiCad. This design features 17 keys (10 number keys and 7 operation keys) . I also used KiCad’s 3D viewer feature to visualize my PCB.
