Tutorial - The FCC and Open Source Hardware
about 3 years ago
I am hoping that my circuit is not going to be troublesome in that sense. It only has an eeprom chip and a accel/gyro both of which are on i2c bus. Other than that there isn't much else, except voltage regulator and a power source. I will look around for the idea of designing to minimize emissions. However - not being an electronics buff, I will need to read a lot :-)
Many thanks for answering. I am relieved that I don't have to go the whole hog :-). I am going to be doing some more testing and then contact some labs and see the cost side of it. At least it does not sound as bad as certification.
Is there a simpleton way of checking for RF emissions before I submit to the lab? I know there are a few like
Now I don't know what use these really are. Just so that I can test for any obvious rampant interference - I was thinking of a micro-vibration motor as a tactile feed back but I know they generate some emf.
I know this is an old post. However, it is one of the few with a lot of information. However as a small time inventor, I am at a loss. I hope people here can guide me in the right direction. I have a prototype that uses the nodemcu v1.0, so essentially it has a intentional radiator that appear to have FCC certification. I can use the bare esp8266-12e or the nodemcu. I prefer nodemcu for ease. I have an accelerometer/gyroscope, a tiny motor and an EEPROM chip added to it and it runs on 3.6v battery power. The device will connect to wifi at home and be used over the home network.
As I understand the discussion, I still need to stand at the FCC door and beg :-( for a Declaration of conformance at the least and even a certification at worst.
As you can understand my predicament, as a small time inventor with dreams of making a device, my biggest cost at present is possible certification. If I use the module that is already certified, can I get away with DOC - seems cheaper? Also any pointers towards analyzing my circuit ahead of time so that I can minimize the risk of failure once submitted to testing lab? I am not trying to avoid the legal requirements. If the FCC needs me to do something, whether I agree or not, I am sure other people know things better than me. So I will subject myself to FCC :-(
If the testing [especially] certification is required, chances are, my project is dead although I already have a prototype and it works great for the purpose - it is a device to enhance gaming experience.
Any pointers, advise, suggestions are all greatly accepted.
