OPTIONAL LED POSITIONING (A for Bottom side, B for Top side) 

ˆ

7A. D1 (colored LED) on the Bottom side. Install D1 (the full-color RGB 
LED) from the bottom side and solder it in place. Orientation of this 
component is critical because it is made up of polarized diode elements. 
Note that the LED has a flat side to help you with its orientation. This flat 
side should be mounted in the same direction as indicated on the 
silkscreen layout and the parts layout diagram (flat side toward R1). 

ˆ

8A. Install R1, a 680 ohm resistor (Marked 681). 

ˆ

9A. Install R2, a 51 ohm resistor (Marked 510). 

                                                        OR 

ˆ

7B. D1 (colored LED) on the Top side. Install D1 (the full-color RGB LED) 
from the top side and solder it in place (make sure to leave the leads long 
enough so that you can top solder it). Orientation of this component is 
critical because it is made up of polarized diode elements. Note that the 
LED has a flat side to help you with its orientation. This flat side should be 
mounted in the same direction as indicated on the silkscreen layout and 
the parts layout diagram by the dashed line (flat side toward J1 & J2). 

ˆ

8B. Install R1, a 51 ohm resistor (Marked 510). 

ˆ

9B. Install R2, a 680 ohm resistor (Marked 681). 

 

OPTIONAL JUMPER PLACEMENT 

ˆ

10. The mounting of J1 and J2 is another choice left to you. They are used 
to select the speed settings of the color change and blink versus fade 
mode operations. When you momentarily close the contacts together, they 
tell the micro-controller what to do. The unit is programmed by default for 
a fairly fast color changing speed (in fade mode) so you may opt to save 
space and not even install them! If you choose to install them on the back 
side of the board you can easily solder the leads. Mounting them on the 
silkscreened top side requires lifting them off the board a bit so you can 
top solder them. Install J1 and J2 if desired. 

 

FINAL COMPONENTS  

ˆ

11. Install C2, one of the 1 uF electrolytic capacitors. These capacitors 
(like most electrolytics) are polarity sensitive so pay close attention to the 
markings. Notice how the positive side of the capacitor’s plastic base has 
small beveled corners? These bevels help to indicate the proper 
orientation of the part. Match these edges with the markings on the silk 
screen of the board to ensure correct positioning. 
As discussed in the pre-assembly steps, tinning one of the circuit board
