Hi, first real post here. I'm a recent fan of mechanical keyboards, so I decided to build my own soon! I was interested in seeing if anyone ever put individual LED lights for their switches on the PCB for the KBD19X. I see that there are sections available for it, but I haven't seen anyone actually do it. Are there problems associated with this?

based on pcb diagram, the KBD19X suppose single color LED on the board. so you can use 3mm LED on them. doesnt support RGB since only supports 2pin LED

Do you think the 1.8mm would be fine instead of the 3mm?

The 1.8mm led will work kbdfans used to carry and offer the service on their website kind of weird they removed it I own 19x and it has 1.8mm installed.
Here is a link to TX keyboards https://www.us.txkeyboards.com/products/led-2x3x3?_pos=1&_sid=39b4b3791&_ss=r you can use leds from their site as well.  :)

most 1.8mm leds seem to use the same pin spacing as the 3mm ones, at least all the ones i ever saw, so yeah it should work exactly the same.

think pin spacing is not a big concern, but rather the voltages send to the led. might be worthwhile asking KBDFans, but i dont reckon any issues with either, even with slight voltage difference and current draws (if any)

led voltages depend on the color, but usually you will use a current regulation as it also depend on temperature, as the led heats up the voltage decrease, the current increase and the led heats up more, maybe red leds could be a problem but i doubt it (red = very low voltage, UV = very high)

Have you made any progress since posting? I'm also waiting on my KBD 19x and would like to know how your project progresses. PS did you figure out if you need a controller when adding the keycap lighting? And will software like QMK work for that kind of setup?

Hi there! I have received my PCB and had some problems while soldering them originally. Be careful about the numpad side for equals as too much solder can cause the entire column to die along with the g key. (Problems that I had). In regards to the LED, I am still working on them, but I have found success with the indicator lights so far. QMK will not do much in terms of the lighting as those LEDs don't have any software capabilities really. I have yet to fully check it out so if I find out something new, I'll be sure to get back to you!
