2.3.2 microSD Card Slot

The BOOSTXL-SHARP128 BoosterPack plug-in module features an onboard microSD card slot. This provides another form of data storage for users.

The microSD card slot can detect if a card is present by generating an active-low interrupt signal on the SD card detect pin. The SD_DETECT signal can be selected between three different pins of the BoosterPack plug-in module using 0-Ω resistors (see Table 1).
