What to verify before ordering

1. Pin assignment and pad layout: the same interface does not guarantee the same pin order.
2. Hold-down positions and termination style (SMT / through-hole).
3. Presence and polarity of the card-detect and write-protect switches.
4. Mated height and card-insertion direction: both published values are shown side by side; judge the difference yourself.
