Connectors & form factors
Through-hole
Components with leads that go through holes in the board, soldered on the other side.
How it looks

CORE3588 bottom side. Every other part is on the top; these rings are where the header's pins come through and get soldered.
- 1Pin 1 of the 3-pin debug header H4: square copper ring around a 1.1 mm hole.
- 2Pin 2: round ring, same hole.
- 3Pin 3. Its hole looks empty only because the 3D model KiCad uses for this header has two pins; the board itself has three plated holes.

- 1A through-hole part on the top side: the pins enter the board here.
How it works
Where it fits
The opposite of SMD / SMT. DIP chips and pin headers are through-hole. CORE3588 has only 11 through-hole pads against 1,046 surface-mount ones.
