This is the exact reason why I didn't see through my plan to build and sell the EspUSB (a very small ESP board that fits inside a USB-A port).

I got 3 units built for myself by PCBWay at a cost of $77. I got quotes of ~$500 for 100 units from Elecrow and Makerfabs, but didn't know what to do with the other 90.

Although I really want this great little gadget to be easily available, I can't afford $10,000 for FCC certification, and therefore I have no solution.

If anybody wants more details, email [e-mail] and we can chat about it on there.

That's not how it work. You start by selling them, prove the concept, and when you have the money, you sort out certifications & whatsnot.

You won't become a unicorn if you think about doing everything _by_the_book_ from day one.

I have enough legal trouble just trying to get a work visa. I'd rather not risk criminal charges, deportation, or worse for a hobby project.

I wonder how the folks that sell on Tindie get around this... https://www.tindie.com/

There are various exemptions for subassemblies and other non-end-user products. Those may not always apply. However, in practice, a product that's sold in small quantities and does not in fact emit egregious electromagnetic interference is unlikely to attract enforcement attention. So a fair bit of skirting of the rules does go on.

Based on the PAL project and WiFi capability, I think the ESP8266 does emit electromagnetic radiation. Whether it's interference or a feature depends on your perspective.

What about using a pre-certified module (eg. Wroom-02 or wroom32)

[peterburkimsher]

Because it won't fit inside a USB port any more.
