3.4. MicroSD   Card   Slot   (J4)  
?
The ? microSD ? Card ? slot ? is ? used ? as ? the ? primary ? means ? to ? boot ? the ? Quick ? Start ? board. ? The ? power ? source ? for ?
the ? microSD ? Card ? slot ? is ? VLDO3_3V3. ? The ? microSD ? Card ? slot ? is ? not ? normally ? configured ? with ? a ? card ?
detect ? feature. ? The ? MicroSD ? Card ? slot ? can ? be ? configured ? to ? boot ? from ? a ? MMCmicro ? card ? with ? an ?
alternate ? boot ? option ? setting ? (see ? section ? on ? Boot ? Options). ?
?
3.5. SD   Card   Slot   (J5)  
?
The ? SD ? Card ? slot ? is ? a ? 5 ‐ in ‐ 1 ? SD/MMC ? connector ? that ? acts ? as ? a ? secondary ? external ? memory ? media ? slot. ?
The ? power ? source ? for ? the ? SD ? Card ? Slot ? is ? the ? auxiliary ? LDO ? regulator ? (DCDC_3V2). ? The ? SD ? Card ? slot ? can ?
be ? configured ? as ? the ? boot ? source ? with ? an ? alternate ? boot ? option ? setting, ? as ? well ? as ? being ? configured ? for ?
either ? SD ? or ? MMC ? card ? operation ? (see ? section ? on ? Boot ? Options). ? The ? SD ? Card ? Slot ? supports ? full ? 8 ‐ bit ?
parallel ? data ? transfers ? and ? can ? support ? SDIO ? cards ? (WiFi, ? BT, ? etc) ? designed ? to ? fit ? in ? a ? standard ? SD ? card ?
slot. ? The ? Quick ? Start ? board ? has ? specifically ? been ? tested ? with ? an ? Atheros ? SD ‐ 25 ? WiFi ? card. ?
?
3.6. SATA   7 ‐ pin   Data   Connector   (J7)  
?
The ? SATA ? connector ? provides ? the ? means ? to ? connect ? an ? external ? SATA ? memory ? device ? to ? the ? Quick ? Start ?
board. ? Commonly, ? this ? would ? be ? an ? External ? hard ? drive ? or ? a ? DVD/CD ? reader. ? Power ? for ? the ? SATA ? device ?
needs ? to ? be ? supplied ? externally ? by ? the ? user ? via ? a ? 12 ‐ pin ? power ? connector. ? It ? is ? possible ? to ? boot ? from ? a ?
SATA ? drive ? by ? making ? OTP ? fuse ? changes. ? Once ? the ? fuse ? changes ? are ? made, ? they ? cannot ? be ? reversed. ?
?
3.7. VGA   Video   Output   (J8)  
?
A ? standard ? VGA ? signal ? is ? output ? directly ? from ? the ? i.MX53 ? Processor ? with ? minimum ? external ? components ?
required. ? Power ? for ? the ? TVE ? module ? of ? the ? i.MX535 ? Processor ? is ? supplied ? by ? VLDO7 ? of ? the ? PMIC ? and ? is ?
set ? to ? 2.75V. ? If ? VGA ? output ? is ? not ? desired, ? it ? is ? possible ? to ? program ? the ? PMIC ? to ? turn ? off ? VLDO7 ? to ?
conserve ? power. ? The ? VGA ? output ? supports ? a ? variety ? of ? video ? formats ? up ? to ? 150 ? Mega ‐ Pixels ? per ? second. ?
Level ? shifters ? are ? required ? on ? the ? Horizontal ? and ? Vertical ? Synchronization ? signals ? as ? well ? as ? the ? VGA ? I2C ?
communications ? signals ? in ? order ? to ? meet ? VGA ? specifications. ?
