This is a segment LED bar without control chip. It has 10 segment LEDs, including of 8 green, 1 yellow and 1 red. It is compatible with bread board and can work with Arduino by adding some current limiting resistors. Since it has 10 pin, it may be complex to control.
Power dissipation per segment: 100 mW
Reverse voltage per segment: 5 V
Continuous forward current per segment: 20 mA
Peak forward current per segment (Duty- 0.1, 1KHz): 90 mA
Derating linear from 25°C per segment: 0.5 mA/°C
Operating temperature range: -30°C to 80°C
Storage temperature: -30°C to 85°C
Solder temperature 1/16" below seating plane: 3 seconds at 250°C NOTE: The side with markings are the cathode connections (-) and the side with no markings are the anode connections (+). You should also use current limiting resistors.
