Suppose one was to design a very simple PCB using an attiny85 running on the internal oscillator driving a few 15mA leds. How much is really involved in passing FCC emissions testing? Would you have to purposely design an antenna to radiate enough EMI to fail or is it the contrary and the design wou…
