Transistors drive 4 RGB Piranha LEDs using PD-LED power or 5V power. Transistors are switched by 3.3v logic level input from PD-LED or other microcontroller. Piranha LEDs surround a 18mm mounting hole which incorporate a proximity sensor.
|Transistor - PN2222A||3|
|Molex - 22-23-2051||5 Pin - Connector header||1|
|5mm - Piranha, Frosted Lens||LED||LED1,LED2,LED3,LED4||4|
If the you are planning on driving these from 5V you need these bill of materials.

|Resistor - 68Ω 1/4W||Green||R6,R9,R12,R15||4|
|Resistor - 220Ω 1/4W||Transistor||R1,R2,R3||3|
If the you are planning on driving these from 3.3V from a PD-LED you need these bill of materials.
Assembly instructions/tips: Through hole soldering. Place resistors 1, 14, 5 and 9 on back side of board before Piranha LEDs. Transistors and header plug are also mounted on the back side of the board.
Warning: silkscreen orientation icon for transistors is incorrect but Base, Collector, Emitter designations are correct. Align transistors according to BCE.
