4. Adding RGB LED's

Step 6a. Soldering the per key RGB LED's.

ALL RGB LED's are placed and soldered from the backside of the PCB with the PCB laying flat on a flat table surface with the LED lens facing down and the markings on the PCB face you are looking at matching.

Under no circumstance using any version of the Lotus PCB's should you try matching the markings on the opposite side, or try soldering the LED's facing you! This will NOT work!

When soldering, double check that the LED end up flat and reasonably centered in the hole. Pay close attention to orientation! Alternating rows have alternating orientation, forming a continues serpentine line down the PCB.

The small triangular marking on the PCB solder side corresponds to the triangular marking on the front of the RGB lens and the cut leg. 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.

v1.11 only 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)

**v1.2x / 1.3x /1.4x ** Bridge the appropriate jumpers, as PER INSTRUCTIONS ON THE SILKSCREEN OF THE PCB!!

For all versions Please note that enabling all 70 RGB LED's at the same time means your power consumption on lighter colors and high brightness will exceed what a normal USB port can supply, and will either make the keyboard become unstable/crash or make the USB ports built in over current protection (re-settable fuse) trigger.

Worst case, you will end up having to re-flash your keyboard and reset EEPROM to clear brightness settings. It's highly recommended to implement a max brightness or similar in the firmware/keymap when using this many RGB's.

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

These six RGB LED's are soldered facing the backside of each PCB and pointed down. Same as above per orientation and alignment applies.
