The ATZB-S1-256-3-0-C is a wireless module (made by Atmel) built around the ATMEGA256RFR2. It is a complete module, including both a ceramic chip antenna, and a small coaxial connector. It also is FCC Certified.
I would like to use this module in my design. As I understand it, I can transfer the module's certification to my design, and then only need to certify the whole design as an unintentional radiator.
Assuming this is true, I only have one problem: the coaxial connector on the board is a good 1mm taller than the rest of the module -- and I don't need it (using the ceramic chip antenna). If I remove the coaxial connector, does that constitute a "change" to the module, and thus nullify its FCC certification?
