Electrical specifications
SBC-A62-J needs to be supplied only with an external 12V
DC
± 10% power supply, with a minimal 35W power rating.
This voltage can be supplied through an optional standard 6.3mm (internal pin, diameter 2.0 mm) Power Jack. Internal pin is V
IN
power line.
As an alternative, +12V
DC
can also be supplied using dedicated internal connector J26, which is a JST
XH series connector or equivalent, p/n B2B-XH-A(LF)(SN), 3A max current per contact, with pinout shown in the
table on the left.
Mating connector: JST XHP-2 receptacle with JST SXH-001T-P0.6 series of female crimp terminals.
2.3.1
RTC Battery
The SBC-A62-J board can be equipped with an optional low-power Real Time Clock embedded on the module (which is a NXP PCF2123). In this case, the board
also mounts a soldered horizontal 3V coin cell lithium battery to supply such a RTC.
The battery used is a not-rechargeable Panasonic BR-1225HCN Lithium coin-cell battery, with a nominal capacity of 48mAh.
As a factory alternative, it is possible to connect external cabled RTC batteries to supply the RTC clock embedded on the i.MX6 processor.
The battery used for this purpose must be not rechargeable, and can be connected to the board using dedicated
connector, J1, which is a 2-pin p1.27 mm type MOLEX p/n 89400-0220 or equivalent, with pinout shown in the table
on the left.
Mating connector: MOLEX 87369-0200 receptacle with MOLEX 50212-8000 female crimp terminals.
Please be aware that such a connector is optional, it will be present only in case that there isn
’
t the additional low-power
external RTC
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-A62-J are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out of
order SBC-A62-J, 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.
