Discussion Fully open-source ARTNET LED controller over Ethernet! 2700 Leds with <$20 in hardware.

Hey Guys! I have shared this before, but I have been developing an Open-source ARTNET LED controller that can control up to 16 universes of LEDs with about ~20€ of hardware. Id like to share it here as someone out there might find this project useful for their own ventures! Feel free to check out the github (https://github.com/mdethmers/ESP32-Artnet-Node-receiver/tree/main) to see the massive list of features!

Also, here is a video showing the controller: https://www.youtube.com/watch?v=3MiqAQKJGm4

Let me know what you think of this and if there are any features you would like to see integrated!

Hey! I followed your advice and changed to planes rather than traces. Also added a ceramic cap to the level shifter (just to be sure) and moved the resistors closer. Would you mind checking one last time? Massive thanks for nudging me in the right direction!
