Hi
I have located a customer who is very excited about the possibility of incorporating wireless into his products. I have tested some prototypes that operate with cheap transmitter-receiver pairs running in the unlicensed 433.92 MHz ISM band.
I am running into some questions around the law when it comes to selling something similar:
1) I'm fairly sure I cannot sell my product using the transmitters I mentioned above, as they aren't FCC certified. Can I buy a pre-certified transmitter (such as those sold by **broken link removed** or **broken link removed**), and interface to it with a microcontroller with USB PC interface, putting everything in the same box, as long as I don't modify the RF section, and still have the overall device maintain the FCC Part 15 certification the radio came with? (I include the PC part because I read something in Part 15 that calls some PC parts unintended RF radiators in some circumstances, and don't understand what part they play in the ability to get something certified).
2) If the answer to #1 is no, are there any other options for me when it comes to purchasing transmitters I can then couple with a microcontroller of my own choosing, or maybe those that come pre-certified with a microcontroller I can further program, for use in a product for commercial sale that don't require me to go through the relatively expensive process of FCC certification?
Thank you for any help!
