 ** Micro USB Power **
-ODROID-C2 power can be provided through USB OTG port instead of DC jack by connecting jumper J8.

+ODROID-C2 power can be provided through USB OTG port instead of DC jack by connecting jumper J1.
 Since ODROID-C2 can consume current more than 0.8Amp by itself while playing a video file or with some peripherals - keyboard/mouse/WiFi dongle - are attached to USB port, we strongly recommend to use 5V USB charger with minimal 1.5Amp+ can be supplied.

 If there is a USB device attached on USB host connector and consumes power a lot, the board might not be booted because the CPU can not be provided enough current. In order to prevent boot failure in such case, especially a USB device consumes a current more than 1A, we strongly recommend to keep providing power through DC jack.

+** Caution : Over-Voltage Protection feature **
+. The power source must be connected to the DC-Jack. \\
+Micro-USB-OTG and other 5Volt rails have not the protection feature.\\
+. Micro-USB power path Jumper(J1) must be removed to enable the Over-Voltage Protection even you use the DC-Jack.\\
+. Maximum over-voltage must be lower than 16Volt.\\
