We have 4 revisions of ODROID-X/X2 base board up to now.
Rev 0.1 2012.6.20 First trial. Only for internal test purpose. We didn't sell this revision. We must cut some signal lines and added wires to make it work. ODROID-X DC Jack wass identical to LCD board DC Jack. But ODROID-X needs 5Volt and LCD board needs 9Volt. So we killed many boards with wrong power supply due to confusion.
Rev 0.2 2012.7.04 Only for internal test purpose too. We didn't sell this revision. Changed DC Jack from 5.5mm to 2.1mm to prevent wrong plug/voltage. Added more understanable texts on silk-screen printing. Changed HDMI resolution setting jumper from 3pin to 2pin Added SD/eMMC booting jumper instead resister soldering.
Rev 0.3 2012.7.13 This revision is used in the first mass production. Slightly changed 5Volt input path. Rubber foot added. Heatsik added. Shipped from end of July.
Rev 0.4 2012.8.08 3.3Volt Buck DCDC converter(U7) was changed from Ricoh RP505K331 to Torex XCL205B333. This change was caused by market situation simply. There is no negative side effect. We couldn't purchase RP505K331 temporarily and we decided to replace it with XCL205B333 with minor modification of PCB. Shipped from early September. Rev 0.3 and Rev 0.4 can be mixed for a while.
