Just a list of ArtNet LED controllers, in no specific order.
let me add the octo:
I’m just in the process of making a teensy 4.1 controller with 40 outputs using ObjectFled in the new fastled libraries if you are into DIY. I’ve done 60universes over 30 outputs previously, this should do 2 or 3 over upto 50 in theory. I always seem to need many outputs rather than long strings. Also have a prototype pcb made, just waiting for some extra parts to finish it…
Just checked, I’m getting upto 50fps with 40 outs and 1 universe per output. Ah, just got 2 universes working, and its at 60fps… 3 universes and its 30fps, thats 20,400 pixels, or 120 universes of artnet…
In case anyone wants to try it, it uses a teensy 4.1 with ethernet board, you have to modify the teensy artent library, by replacing the Artnet.h with the one included, in C:\Users\YOUR_NAME\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.59.0\libraries\Artnet
And a prototype board for it https://www.dropbox.com/scl/fi/3i55gifj9zb8sxv6oj4wz/Teensy40.zip?rlkey=xs4bkkk41teybuzf2ztap0kpm&dl=0 which uses 74HCT245 chips for 3.3-5v buffering, and 100ohm resistors, there is a linear voltage convertor spot if needed, otherwise wire across the pins to take a 5v in to the board. It needs some extras like a zener diode etc, but it should work as is. Although I havent tested all the pins yet…

Set the LED start pin to 0, its on 5, my mistake, and the pins aren’t in order yet… Board is tested now and all works though. Its a pretty quick build, and not that hard despite SDM components (with 2 pairs of glasses for us old fogeys…)
thanks for sharing @catweasel .
similar to your board there is also a PCB called Pixelpusher which is currently out of stock but the board design is opensource and he also has splitter/powersupply breakout boards for RJ45 plugs.
the guy making it also has a e.131 (sACN) library for teensy in his github (disclaimer: i never tried it).
Hi @Motzi I actually was using his board previously to this one and did a port of his SACN code to artnet, and this is it re-ported to pure fastled. I lost the RJ45’s as I need to send my signal in groups of 5’s rather than 4’s, so I am using screw terminals for the pins.
So I can confirm it all works as it should too.
I would also like to remind you that I am an experienced electronics developer. Over the years, I have gained a lot of experience in developing electronics of various levels and complexity. I have experimented quite a bit with assembling custom lighting devices using custom boards and WLED firmware.
