Sort of related question: How often does the FCC go after small scale electronics suppliers? Like, say I wanted to make a small microcontroller based device for cars to control the air compressor for air-ride suspension (just an example).
Technically, since this device has a digital clock, it needs to be certified, no?
How do companies like Arduino get away with selling devices that presumably aren't certified?
- alyandon 6y agoAt a guess - that probably falls under FCC Part 15 rules since it isn't an intentional transmitter. As long as it isn't causing interference it'd be compliant.
- skim_milk 6y agoI think the FCC only went after Hobby King since they were selling radio sets that emit radiation beyond the legal limits. I can't find the limit for 5ghz radio on Google without being bombarded by 5g conspiracy theories, but I think the limit is something absurd like 5 milliwatts, or just barely enough for your Wifi router to pick up your phone through a single sheet of drywall at 15 feet away. If you're a Yankee that likes to fly drones like me, you have to buy radios from China that emit 10x the FCC-imposed limit in order to unlock the ability to fly behind one medium-sized tree at 150ft away - and even then at that power level it still doesn't interfere with anything. Leave it to the FCC to go after some harmless hobby instead of rubbish GE microwave ovens that cut out my home's wifi!

They were selling units that operate in the aircraft navigation and traffic avoidance bands, as well as in the GLONASS band.
