2.3 Powering the board

There are three possible ways of powering A13-OLinuXino – via external supply using the power
jack, via a battery using the battery connector or via the USB OTG connector. Depending on your
preferred way of powering A13-OLinuXino you might need additional hardware.
The preferred way of powering board is via the PWR jack with 6Vdc to 16Vdc with a power of 6W
(e.g. 6Vx1A to 16Vx0.4A). This will make the board fully powered and able to power all the
peripherals connected to it.
When powered by the typical 3.7V Lithium-polymer battery the board will be fully functional and
you will be able to operate with most of the peripherals. However when using all three USB-A
connectors and an LCD connected to the LCD_con it might cause flickering and not sufficient
power. If you suspect the power is not enough for the peripherals you have connected use the PWR
jack.
The board can be also powered by the USB OTG connector (mini USB standard) but the voltage
provided is not enough to power a possible LCD connected to the LCD_con. However, this power
option is capable of driving the board when using external display connected to the VGA connector.
If you have a standard LCD display connected to LCD_con, Android and WIFI running the typical
consumption is between 150mA and 350mA depending on the current load. While the board is in
stand-by mode it consumes a minimum of 60mA. All the three approximate values above were
taken when I applied 12V to the board.
Important! Avoid disconnecting the power supply while Android or Linux is running, since that
might corrupt the operating system and you will need to install the OS again (for Android install
instructions check chapter 2.6. Use the PWR_BUT before disconnecting the supply.
If the board has entered power-down state you can bring it back without restart using the
PWR_BUT.
For the European customers we sell a power supply adapter 12V/0.5A – SY0612E. We also sell
USB OTG to USB type A cables if you lack such.
