Nordic Semiconductor Modules: BLE Sourcing in China
1 resources tagged with "Nordic Semi"
Nordic Semiconductor's nRF52 family (nRF52840, nRF52832) powers a large share of the BLE 5.x modules built in Shenzhen. Chinese module makers package these SoCs into pre-certified modules carrying FCC and CE grants, so you inherit the radio approval instead of running your own RF lab pass. Genuine Nordic silicon matters here — the part number, flash size, and FCC ID should all line up with Nordic's published reference.
When sourcing Nordic-based modules, confirm the module's FCC/CE grant covers the antenna design you're actually shipping, and ask whether the supplier uses genuine Nordic parts versus a cheaper SoC swapped under the same housing. A grant tied to a different antenna voids your inherited certification.

FAQ
Is an nRF52840 module's FCC certification reusable for my product?
A modular FCC grant on the BLE module can transfer to your product if you use the approved antenna and follow the integration conditions in the grant. Change the antenna and you typically need a Class II permissive change or new testing.
How do I confirm a Chinese supplier uses genuine Nordic silicon?
Ask for the Nordic part marking, cross-check the FCC ID against the module's listed SoC, and request a sample for decap or X-ray if volume justifies it. Genuine nRF52 modules cost more than EFR32 or generic alternatives, so an unusually low price is a flag.
