Took several weeks from idea to the one productive hour because of my non medicated ADD.
The idea is to see easily all the 120 RGB LED pixels when programming.
Now I can add any boards like Arduino, ESP32 to the breadboard, containing level shifter with four channels (74HCT125) for the signal to the led strip. Just move one jump wire and you can change the signal between the development boards.
