Kits and test equipment are generally exempted from FCC, if they are unintentional radiators [1]. Unintentional radiators don't get certified or get an FCC ID, instead it is based on self declaration. You should do the test (a couple of hundred dollars) to make sure it passes. There are a number of labs locally and abroad that will do it. It might make sense to use a local lab for pre-scan and then pay an off-shore lab to do the full test. If you have any kind of radio transmitting part, i.e. an intentional radiator, then you should use a pre-certified module or otherwise pay about 5-10K to get it certified. 1. https://www.sparkfun.com/tutorials/398 https://www.sparkfun.com/tutorials/398
