BELEUCHTUNG
Der Betrieb der Hintergrundbeleuchtung erfordert eine Stromquelle oder einen externen
Vorwiderstand zur Strombegrenzung. Die Flussspannung der gelb/grünen Beleuchtung liegt
zwischen 3,9V und 4,2V und die der weißen Beleuchtung zwischen 3,0V und 3,6V. Bitte beachten
Sie ein Derating für den Betrieb bei Temperaturen > +25°C!
Achtung: betreiben Sie die Beleuchtung nie direkt an 5V; das kann zur sofortigen Zerstörung führen!
