SD-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 6 pin-out based modules may provide a SDIO
interface shared with GPIO signals. Therefore on COM Express® Eval Type 6 a
SD-Card connector is available. Please check the documentation of your module
if SDIO is supported and how to enable.
This carrier features an SD Card slot at U38
The onboard GPIO connector is at J56
