Mating connector types for the customer's application offered by Molex:
Figure 10: Mating board-to-board connector 53748-0808 on application
• 53748-0808 SlimStack Plug, 3mm stacking height,
see Figure 12 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 assignments are listed in Section
6.5, pin locations are shown in Figure 8.
