IoT Modules from China: BLE, Wi-Fi, LoRa, Zigbee
5 resources tagged with "Iot Modules"
The wireless module is usually the part of an IoT product where certification and chipset choice matter most. From Chinese suppliers you can source BQB-certified BLE 5.x modules on nRF52840/nRF52833, ESP32-S3/C3 Wi-Fi+BLE modules, SX1262 LoRa modules split by region (EU 868 MHz, US 915 MHz), and Zigbee 3.0 modules on TI CC2652 or Silicon Labs EFR32 with a Matter-over-Thread path. Typical OEM MOQs run from 500 units for LoRa modules to 1,000 for Wi-Fi and Zigbee, with PCB, ceramic, or U.FL antenna options changing the RF test report.
An IoT module bundles the radio SoC, RF front-end, and antenna interface into a pre-certified board you drop onto your carrier PCB. The pitfall is treating modules as interchangeable — band, antenna type, and certification scope (FCC/CE/RED/TELEC/BQB) all need to match your target market before you commit to tooling.

FAQ
What MOQ should I expect for OEM IoT modules?
SX1262 LoRa modules often start around 500 units; ESP32 Wi-Fi+BLE and Zigbee (CC2652/EFR32) modules typically start around 1,000. Antenna and firmware customization can raise the minimum.
Which certifications come pre-loaded on Chinese IoT modules?
Well-run suppliers ship modules already carrying CE/RED and FCC, plus BQB for BLE and TELEC for the Japanese market. Always confirm the certificate number maps to the exact module variant and antenna you are buying.
How do I choose between PCB, ceramic, and U.FL antennas?
PCB or ceramic antennas keep cost and assembly simple for compact devices; U.FL lets you use an external antenna for range or metal enclosures. The antenna choice is part of the RF certification, so decide before testing.
