OLIMEXO 2012 OLinuXino MICRO User s Manual 2 4 Powering the board The board is powered either via the PWR jack or via a battery It should be supplied by 5V source with maximum current of 1A from the power jack All measures below are taken at 5V If measuring the current consumption it should be around 0 06A before initializing all the peripherals IMPORTANT We discovered a situation which might leave some of the SD cards iM X233 OLinuXino SD in unrecoverable state when powering OLinuXino MICRO The problem might occur if two specific conditions are met simultaneously 1 Plugged iMX233 OLinuXino SD micro SD card with holographic sticker on its back side some of the cards we have distributed are from a brand that places holographic sticker on their backs the other half lack such a sticker 2 Plugged USB SERIAL CABLE F at the moment when powering the board If you happen to have received SD card with holographic sticker on its back side and you use it with OLinuXino MICRO and you plug USB SERIAL CABLE and then you power the board there is a chance of malfunction of the SD card There are two possible workarounds to protect the SD card The first one is simpler and the second one requires some soldering experience Workaround 1 First insert the iMX233 OLinuXino SD card and then power the board and if powering the board from a battery also press the PWR button Wait 4 5 seconds and then connect the USB SERIAL CABLE F After the i
