microSD Card Connector
The
COM Express Type 10 Mini Carrier
provides a Micro SD Card Slot at P4. This Micro SD Card slot
sources the SDIO interface from the COM Express modules GPIO pins.
** Note this SD card slot will ONLY operate if the COM Express module provides the SDIO interface over the
GPIO pins. Some COM Express modules may have this as a BIOS setting, others will be strictly a hardware
option. See below for the SDIO / GPIO mapping **
