Hi,
I am designing a board that has 9 LEDs (SK6812) and a microcontroller (Atmega328P) that accepts UART commands and lights up the LEDs.
The design is almost ready, I have doubts about the earthen loops. I learned more about earthen loops only today. GND comes only through the terminal block located on top. The ground mounting holes do not have contact with the metal case, as the screws will be screwed into plastic.
Tell me, are there any earthen loops here? If so, how can I avoid them? The board has two layers.
