Howdy, I have a person/client who wants to use one of my boards in a commercial product. They are concerned about getting FCC certification for it and I really have no experience with it. I think they can "dodge" the UL stuff by simply using an external UL approved power supply/wall wart (so everything inside the product is 5volts), but as I understand the FCC stuff, if you have a clock/oscillator over 9Khz, it needs to be certified. If anyone has gone through this process, I'd really like to hear some details about it. Particular questions: 1) Are there any exemptions for small batch/lot products (these will mostly be "art works")? 2) Did you have to do a lot of shielding? The controller is a PIC running at 8Mhz doing a lot of RGB LED PWM stuff (www.rgbled.org). I don't think it throws off that much RF, but... 3) Did you use one of those FCC certification shops? 4) Do you have a rough idea how much the process costs? This could be for class B certification (residential)? 5) Did you also get a CA certification too? If so, was the pricing similar? Of course, while all the questions are important, #4/5 are really what are going to sink/float the product.
