Mating connector types for the customer's application offered by Molex:
Figure 11: Mating board-to-board connector 53748-0808 on application
• 53748-0808 SlimStack Plug, 3mm stacking height,
see Figure 13 for details.
• 53916-0808 SlimStack Plug, 4mm stacking height
Note: There is no inverse polarity protection for the board-to-board connector. It is therefore
very important that the board-to-board connector is connected correctly to the host application,
i.e., pin1 must be connected to pin1, pin2 to pin 2, etc. Pin locations are shown in Figure 9.
