LED module which provides a red and a green LED. These LEDs are connected with a common cathode.
Resistors are needed for different input voltages.
Vf [typ]= 2,0-2,5V
If= 20mA
Pre-resistors:
Rf (3,3V) [Green]= 120Ω
Rf (3,3V) [Red]= 120Ω
[for example using ARM CPU-Core based microcontroller like Raspbarry Pi]
Rf (5V) [Green] = 220Ω
Rf (5V) [Red] = 220Ω
