Communication Modules & PCBA
In-house designed communication modules (10+ models) and PCBA solutions that bring your hardware online. This is the material starting point of product intelligence.
Delivery Module and PCBA supply, hardware debugging support and help with network certification. Connects to the Xiaowei IoT cloud platform for one-stop intelligence.
How it works
Four steps, from module selection to a working app
Module and PCBA supply, hardware debugging support and help with network certification. Connects to the Xiaowei IoT cloud platform for one-stop intelligence.
-
Choose a module
Pick a model by protocol, power, range and certification needs, or go straight to a PCBA.
-
Build it in
Hardware debugging, production testing and firmware flashing support to shorten your product R&D.
-
Connect to the platform
Once on the Xiaowei IoT Cloud Platform, you get device management, OTA and remote control.
-
Add App / AI
Add smart features when you need them. No need to buy everything at once.

Communication Modules & PCBA
From modules to PCBA, chosen by product form
The communication module gets the product connected. The PCBA fits it into the finished device. Each line can be bought separately or delivered with the cloud platform and app, mainly for consumer electronics, small appliance and smart home manufacturers.
