Ergodox RGB LED
« on: Wed, 29 June 2016, 19:05:23 »
Hi Everybody,

I'm new to Ergodox. Planning to build a custom keyboard. I'm trying to add RGB LED under every single key. Want to be able to change led colors based on some presets, caps lock and numlock presets. Is there something already developed for RGB LEDs? Is the Tweesy 2.0 capable of handling that many LEDs?

Any help is appreciated.

Thanks,
Ruben

The biggest limitation to doing this is PCB support. The regular Ergodox PCB doesn't support LEDs at all, and the Ergodox Infinity only supports single color LEDs. So if you want RGB support, your options are either to hand wire or fabricate a custom PCB.

LED's are a bad idea.

I had a girlfriend once. She saw my flashing Light-Emitting-**** and has never spoken to me since. Don't put LED's on a keyboard.

I'd be afraid too. Light emitting diodes should be fine though.


As has been mentioned, the ergodox PCBs available do not support addressable RGB LEDs. I'd want to look at a wiring diagram, but it may be possible to get bi-colour LEDs -- like on some of the newer Ducky Shine models -- working with the infinity ergodox PCB.

Note that this appears to be one LED per side, rather than a single LED per key.

Also, FalbaTech's wireless backlit ErgoDox is apparently (still) in development.

We are working on our own Ergodox (bluetooth with RGB lighting), we had couple failed prototypes, but I can tell you, soon you'll have it :)

So ... I have ergodox keyboard from falbatech, is it possible to put LEDs under each keycap, one color LEDs? If so Where do I connect the LED ?

PCB have not this possibility
(has not holes and tracks for leds)

i think teensy does not have enough pins for adiing separate keyled matrix

it can be done with additional io expander+ software I2C on unused pins... but you need to handwire led matrix

No.

There are only 3 positions for LEDs on each PCB and they're clearly marked on the Falbatech board.  The most you can have on any one 'Dox is 6 (3 per side) and I believe it requires some additional code in the firmware to use all 6 at once.
