PCB for Indicator with installed resistors.

Specifications:
LED nests: 2
Recommended LED type: 3.0-3.5 V
LED size: 3 or 5 mm

Our universal PCB for indicator with parallel LED connections and installed resistors allows using LEDs of 3.0-3.5V. Modern LEDs have voltage parameters varying from approximately 1.2V to 3.5V. Most custom cockpits built by flight simulator enthusiasts take power for indicators from 5V USB port. If each LED in the pair needs voltage higher than 2.5V resulting overall voltage should be more than 5V. Parallel LED connection allow use 3.0-3.5V LEDs without loss of brightness.

PCB obtains power through mounted 3-pin connector, where "+" is on the 1st leg marked as +5V. Ground is on 2nd leg which is connected with 3rd leg. As shown on the picture, that allows one by one Ground connection of all indicators used in the system without spending a lot of wiring. PCB has central hole which can be used together with  PCB Screw for better mounting to indicator box.

Please contact us if you want to power up PCBs using 12V power supply. 12V PCBs are available for custom manufacturing.
