DZ65RGB underglow mod
Posted: 18 Aug 2023, 11:51
Hello guys,
I have a question for an upcoming project. I really like the DZ65RGB in my Tofu acrylic case, but sadly it doesn't have unerglow, only per-key RGB, and there are only solder PCBs with underglow. So I thought, why not adding underglow myself.
Idea 1: Piggyback only power for LED strip
This will be the easiest option, as power can be directly drawn from the USB pins. Somebody already did this with a remote controllable strip, but in the perfect case I want QMK control.
Idea 2: Finding empty pins to connect some WS2812Bs
At first glance I couldn't find any exposed pins on the PCB, so this idea might not be viable.
Idea 3: Using existing per-key LEDs
This is my favorite idea so far, as it seems quite "simple". I thought about adding the same type of LEDs that are already mounted as per-key LED and just "steal" the signal for the underglow. This way the lighting can be reasonably controlled via "VIA" (pun intended).
So my question is, what's the best way to identify the type of LED used? The QMK firmware is configured to use the is31fl3731 LED matrix controller, but I have no idea what kind of LEDs this thing is driving.
And if it's some kind of WS2812B, can I just add a second one parallel to the same data line?
