Title: How do I know what LEDs to buy for my board (TX-84V2)
Post by: fuzzybaffy on Tue, 08 October 2019, 23:25:53

So I'm about to build my TX-84V2, but I realized while watching TaeHa, who happened to be building a TX-CPv2 at the time, that I need to buy and solder my own LEDs for the PCB.

During his stream, however, he apparently ran into some issues with the keycaps hitting the LEDs, and someone on stream said it's because he was using 2x3x4 LEDs.

I'm a complete noob when it comes to custom building (this is my first build), so how do I know what LEDs I need to buy? I did a search for "2x3x4 LED" on Amazon, and I found this: https://www.amazon.com/Rectangle-Transparent-Lighting-Electronics-Components/dp/B01C5HL0PO/ref=sr_1_2?crid=2VJDTGSNF9T6B&keywords=2x3x4+led&qid=1570594974&sprefix=2x3x4%2Caps%2C198&sr=8-2 (https://www.amazon.com/Rectangle-Transparent-Lighting-Electronics-Components/dp/B01C5HL0PO/ref=sr_1_2?crid=2VJDTGSNF9T6B&keywords=2x3x4+led&qid=1570594974&sprefix=2x3x4%2Caps%2C198&sr=8-2)

But those don't look like RGB LEDs, while I believe the TX84 PCB supports RGB? Also, I want to avoid having the keycaps hit the LEDs, so wouldn't I need to buy different sized ones? Where would I find the appropriate LEDs?

Thanks in advance!

Edit: After doing some searching, maybe my PCB doesn't actually support controllable RGB? So I either have to get single color, or RGB that just cycles through the colors. But what size would I get? Would 1.8mm be appropriate to prevent the keycaps hitting them?
