I have two WS2812 RGB LED matrix LCDs and 16 RGB LED RPMs. All components have their own arduino NANO with their own power supply in the USB HUB. I divided both two matrix LED panels into two separate indicators - they work fine. Alas, if I also connect the RPM 16LEDs, they will not connect. I noticed that either the matrix LED always connects and communicates, or only the RPMs LED - never together - is there a solution? Thank you!]]> Projects xvawe https://www.simhubdash.com/community-2/projects/rgb-ws2812-led-matrix-and-rpms-ws2812leds-dont-work-togeder/#post-10141
