Electrical specifications
SBC-C23 needs to be supplied only with an external 12V
DC
± 10% power supply, with a minimal 20W power rating (SBC-
C23 power consumption by itself is around 5W, more power is required for the possible attached devices).
This voltage can be supplied through a standard 6.3mm (internal pin, diameter 2.0 mm) Power Jack. Internal pin is V
IN
power line. DC mating plug diameter 5.5mmm, internal hole 2.1
As an alternative, +12V
DC
can also be supplied using dedicated PCB Terminal block
CN76, which is a Phoenix Connector p/n MC 1,5/ 2-GF-3,81.

needed.
The board can also be supplied by an optional 3.7V 2200mAh rechargeable battery (factory option), which can be an EEMB LIR18650 or a cabled RRC 100587 battery pack (3.6V
2200 mAh) with NTC reading.

RTC Battery
The SBC-C23 board can be equipped with an optional low-power Real Time Clock embedded on the module (which is a NXP PCF2123).
If the board is not equipped with the optional rechargeable battery, then it will be available a soldered horizontal 3V coin cell lithium battery to supply the RTC.
The battery used is a not-rechargeable CR1225 Lithium coin-cell battery, with a nominal capacity of 48mAh.
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 SBC-C23 are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of order
SBC-C23, 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.
