Is nrf24l01+ from Nordic Semiconductors FCC certified ? It is hard to find out from their datasheet whether FCC approved ? Is it FCC approved ?
If it is approved and I use it in my PCB and control it via my ARM cortex processor, do I need to get the entire PCB board FCC approved ?
Also, I am using sierrra wireless HL series modem chip which is FCC approved. This will also be on my PCB. So, do I have to get my PCB FCC approved again although my modem is FCC approved ?
a chip cannot be certified.
A product with system and a specific antenna arrangement can be tested for certificaitno.
If you PCB is a one of a kind, no need to FCC cert.
If it’s to be a product sold in the US, plan on $30K.
A cellular modem has to be approved by the cellular network operator, independent of the FCC. And being in licensed spectrum (unlike 2.4GHz), the rules differ.
If you are making a product and don’t know the above… you better hire someone who does.
