IoT Module Sourcing & Supplier China

IoT module sourcing requires genuine technical depth. The difference between a Semtech SX1276-based module from a qualified manufacturer and a counterfeit or poorly-characterized part can cost you months of debugging and a failed FCC certification.

What We Source

• LoRa / LoRaWAN modules and gateways (868 MHz EU, 915 MHz US, 470 MHz CN)
• BLE 5.x modules (nRF52, ESP32-based)
• WiFi modules (ESP32, W600, RTL8720)
• LTE-M / NB-IoT modules
• Zigbee and Thread modules for smart home
• Industrial sensors (temperature, humidity, CO2, air quality)
• RS-485 / Modbus gateways

Common Challenges

Genuine vs. counterfeit components — We verify chip origin through manufacturer-authorized distributors and run spot-checks with spectrum analyzers and protocol analyzers on samples.

Regulatory band compliance — A module sold as “LoRa 868” may actually transmit at 915 MHz. We verify RF compliance with spectrum analysis before bulk orders.

Firmware and AT command documentation — Many Chinese module makers have inadequate English documentation. We evaluate documentation quality and work with the factory to fill gaps before your engineering team hits integration problems.

Small batch economics — IoT hardware often starts at 100–500 units. We negotiate MOQ flexibility and blanket orders with scheduled releases to get volume pricing at small quantities.
