    Very clear and concise explanation.

    Thank you

    You covered a few simple fixes. Avoiding long traces, simple RF filter, complying with certified module like the ESP32. Please follow up with a similar 5 minute video showing examples. Is this why I occasionally see blocks of traces that double back and forth serpentine like?
    Thanks for a great video.

    Thank you for the video! I'm planning to sell one project one day and there is just so much to consider besides all the financial and other legal stuff as well

    Great video! Would soldering on an external antenna to an ESP module that’s already FCC approved, cause your device to violate it?

      You can buy ESP module with soldering pad for the antenna that are fcc approved!? Don't think so, they have UFL connector not a soldering pad. The other module have the PCB antenna on it. If you solder your own antenna, then needs testing because you don't know if that antenna is the right frequency range for that module.

      As soon as you alter the module in ANY way, or implement the module in your design that is different to the "tested and approved" guidelines, you invalidate the certification on the module and you are back to a full intentional radiator test.

      Yep, @Unexpected Maker is right on. Often with modules that have an external antenna port, like some ESP32's do, as long as you use the same type of antenna, with the same or lower gain/power you're OK. But that's definitely a question to relay to the FCC or your test lab about.

      You have to look up the files that were submitted to the FCC for this module. If the antenna you are going to use is listed in the documents, and was tested, you can fall back on that FCC approval. If the antenna is not mentioned, you need to recertify your device.

    Testing an intentional radiation device for FCC certification would cost roughly $10,000AUD not six figures. This involves testing for Radiated and Conducted Emissions for mains powered devices for around $4k or only Radiation emission for battery powered devices for around $3k which falls under FCC Part15B and additional test on antenna port which involves power spectral density, occupied bandwidth, maximum output power etc for around $4k plus test report, DOC and submission to FCC for FCC ID and labelling.

    What about unintended radiation from a hobbyist- built circuit that isn't going to be sold to anyone?

    this is why china is getting ahead of you guys.
