CE mark

[tllim]

I think, any device or electronic independent accessory will need the CE certification. In case you assemble all devices together, a new CE certification is required.

I agree with you. The important thing is that the accessory is for end-users. If it were components only for companies that use them in their products, it would be an other case. But this components are directly addressed to end-users with no special knowledge in EMC for example.

But I'm not an expert. So there is a good chance that I'm wrong.

I am also not an expert, and I will seek the CE certification lab for their response.
