Would you mind elaborating on what felt problematic, please? I looked into the CE requirements a few years ago and it didn't seem like a large barrier for small electronic devices - nothing that wouldn't be expected in a safe design already, such as ensuring proper earthing or using lead-free components. I'm curious to know what you found so that I don't have any unpleasant surprises should I go ahead with a hardware product! Maybe konschubert also has experiences they could share here.
