FCC testing required?

(1/2) > >>

Hi, I'm a new engineer and I've been contracted to design a product for a client. It's a simple micro-controller board for storm water management, nothing crazy. I've been reading into FCC regulations for selling products, and I believe I need to have compliance testing done.

Here are some relevant details:

* 24v input, powered either by a solar system or off the shelf mains converter
* optional cellular module (external unit, already certified)
* 8MHz microcontroller
My client is a contractor and plans to install these as part of a system inside of a cabinet, and also wants the option to sell the individual boards later.

Sorry if this has been asked a million times, this sort of thing can be stressful.

There are some interesting exemptions:

Thanks for the reply.

I've read through those documents, and unfortunately I don't think my device falls under any of the exemptions.

Just wanted to make 100% sure.

JohnnyMalaria:
Hmm, I wonder if there's scope for exemption in this depending on your client's target customers:


--- Quote ---(b) A digital device used exclusively as an electronic control or power system utilized by a public utility or in an industrial plant. The term public utility includes equipment only to the extent that it is in a dedicated building or large room owned or leased by the utility and does not extend to equipment installed in a subscriber's facility.

(c) A digital device used exclusively as industrial, commercial, or medical test equipment.

Is this device similar to anything else on the market? If so, does they have FCCIDs?

This design is a replacement for something he had someone else make. From what I've been told I wouldn't be surprised if it wasn't tested, but that is a good lead. Thanks for all the help.
