4. Adding RGB LED's

Step 5. Soldering the per key RGB LED's.

The RGB LED's for the per key lighting are soldered from the backside of the PCB with the PCB laying flat on a flat table surface with the LED lens facing down.

If using the standard 1.6mm PCB thickness the LED's are of the same thickness, and placed inside the cut-out, the solder pads on the LED and PCB should be very close to level with each other. Pay close attention to orientation!

The small triangular marking on one corner of LED body marks pin 3 (Data in) and corresponds to the marked soldering pad on the PCB on the solder side facing you. Place the LED with the lens facing down, aligning the triangle with the mark.

Note that when looking at the PCB from the front once soldered, you are looking at the markings for the reversed PCB, and the markings will NOT line up.

The per key and under-glow RGB LED's form one continuous data line, starting with the per key lighting, and ending with the six under-glow LED's. If you prefer too, you can leave out the under-glow LED's and the per key lighting will still work, but using the under-glow LED's without per-key lighting is not possible. (Unless you do some creative bridging with a wire)

Please note that earlier versions of the PCB 0.x-1.0x had various errors, ranging from incorrect wiring (reversed data line, 0.x) to incorrect silkscreen (1.0x). If you ordered one of these, I apologize! Double check the visible GND signal and align from that

Step 6. Soldering the under-glow RGB LED's.
