6 – 150 

Ω

 LED resistors where the Red, Blue, and Green (Grn) resistors are located.

18 – 5mm white LEDs as marked (

Important: notch goes to the left as shown

).

Connect one ground wire to either the Red (R), Green (G) or Blue (B) LED ground point as marked.

Connect one wire to the LED +12V common (C) power supply as marked.

Assembling the PCB with 9 LEDs

Please purchase the following parts:

1.

3 – Suitably-valued 

¼

 W resistors (1.70mm x 3.20mm size, through-hole)

2.

9 – 5mm or Piranha LEDs (your choice but keep similar colours in one set)

3.

1 – RGB MR-16 PCB

Assemble and solder these parts in the following order within the 

Nine LED

 area (refer to PCB outline above):

3 – LED resistors where the Red 1, Blue 1, and Green 1 resistors are located

9 – 5mm LEDs as marked in the 

Nine LED

 area (

Important: notch goes to the left as shown

)

Connect three wires to Red, Green and Blue LED ground points as marked

Connect one wire to the LED +12V common power supply as marked
