7.4 Panel Power
The panel power jumper J2 sets the panel supply voltage. For this setting a solder jumper is important. The
board is delivered with the solder jumper equipped as shown on the following picture.
In this case the board is configured so that 3.3V or 5V panel supply voltage can be selected with jumper J2.

When a panel supply voltage of 12V is needed the solder jumper has to be set to the red marked position of
the following picture. It is important that only one of those two solder jumpers is equipped. When the 12V
solder jumper is set the 3.3V solder jumper has to be removed.
In this case the jumper setting (2-3) for 3.3V leads to a panel supply voltage of 12V.
Note: All soldering works must be done in a professional production environment. To avoid loosing the guarantee for your product
please contact the board vendor before you make any solder modification on the JRexplus-DC.
