5.5 µSD-CARD / Module GPIO
The SD-Card standard is a standard for removable memory storages designed and licensed by the SD Card Association
(http://sdcard.org). The card form factor, electrical interface and protocol are all part of the SD Card specification.
COM Express® Type 1 and Type 10 pin-out based modules may provide a SDIO interface shared with GPIO signals.
Therefore on COM Express® Reverence Carrier Type 10 a µSD-Card connector is available. Please check the
documentation of your module if SDIO is supported and how to enable.
Close configuration jumper39 (default) to enable µSD-Card Slot J47 or open J39 to enable GPIO pin-header J38.
