Connection of the LEDs for the front light
You may connect up to two white LEDs for the front lighting to the
voltage output of the module. These LEDs are not controlled by the
stored software. They light as soon as the module is connected to the
power supply.
Connect the anodes (+) of the LEDs to the soldering point X2 and the
cathodes (-) to the soldering point X3.
Caution: The LEDs for the front lighting must be operated via
!
series resistors (recommended value: 100 ). Otherwise the
connected LEDs are damaged and the circuit may not work as
intended.
