Electrical specifications
The UDOO x86 board needs to be supplied only with an external 12V
DC
± 5% power supply, minimum 40W for basic functionalities
recommended.
This voltage can be supplied through a standard 6.3mm (internal pin, diameter 2.0 mm) Power Jack (CN21). Internal pin is V
IN
power line.
2.3.1
RTC Battery
For the occurrences when the module is not powered with an external power supply, on board there is a cabled coin Lithium Battery to supply, with a 3V voltage,
the Real Time Clock embedded inside the Intel
®
SoC.
Battery used is a cabled CR2032-LD Lithium coin-cell battery, with a nominal capacity of 220mAh.
The battery is not rechargeable, and can be connected to the board using dedicated connector CN5 which is a 2-pin
p1.27 mm type MOLEX p/n 53398-0271 or equivalent, with pinout shown in the table on the left.
Mating connector: MOLEX 51021-0200 receptacle with MOLEX 50079-8000 female crimp terminals.
In case of exhaustion, the battery should only be replaced with devices of the same type. Always check the orientation before
inserting and make sure that they are aligned correctly and are not damaged or leaking.
Never allow the batteries to become short-circuited during handling.
Batteries supplied with UDOO x86 are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of
order UDOO x86, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European Directive above
mentioned. Even when replacing the batteries, the disposal has to be made according to these requirements.
