nRF52 BLE Modules: Sourcing & Certification Guide
1 resources tagged with "Nrf52"
The nRF52 series is Nordic's mainstream BLE 5.x SoC family, with the nRF52832 (512KB/64KB) and nRF52840 (1MB flash, plus 802.15.4 for Thread/Matter) as the two parts Chinese module makers stock most. A pre-certified nRF52 module lets you inherit an FCC ID and CE grant rather than booking your own radiated-emissions test slot. Module pricing tracks flash size and crystal accuracy, so spec the variant your firmware actually needs before comparing quotes.
When you source nRF52 modules, the practical question is nRF52832 vs nRF52840 — the 840 adds USB, more flash, and 802.15.4 for mesh/Matter. Pick based on firmware size and radio protocol, and verify the supplier's grant matches that exact variant.

FAQ
Should I choose nRF52832 or nRF52840?
The nRF52840 has 1MB flash, native USB, and an 802.15.4 radio for Thread and Matter; the nRF52832 is cheaper with 512KB flash and BLE-only. If you need mesh, Matter, or large firmware, go 840; for a simple BLE sensor the 832 is usually enough.
Do nRF52 modules from China come pre-certified?
Reputable Shenzhen module makers sell nRF52 modules with existing FCC and CE RED grants you can inherit. Confirm the grant covers your antenna and check the FCC ID against the listed SoC before relying on it.
