Amphenol 101-00565-64 SD
/ MMC socket with card
detection switch.
The SD card specification details an operating voltage of
between 2.7 and 3.6V. If using the SD card, it can ONLY be
used when VDD_HV_A (and PER_HVA) jumpers are set to 3.3V.
Inserting an SD card with VDD_HV_A / PER_HVA set to 5V will
result in card damage.
Card Detect: Grounded when Card Inserted, Pulled high when card removed
Write Protect: Grounded when NOT protected, Pulled high when protected (or card removed)
