Solution Options
Option 1: Write Your Own Lighting Logic
- Ideal for developers who want full control over lighting behavior.
- Choose your own communication module (e.g., LoRa, Bluetooth)
- Write your own control logic inside the module
- PCBA provides I/O documentation (e.g., relay control, sensor readout)
- Best for custom use cases: timer-based control, scenes, adaptive dimming, etc.
✅ Example:
An Australian customer used a Bluetooth module to run their own dimming algorithm.
Option 2: As a Pure Data Bridge
- Best for teams that want plug-and-play functionality with minimal development.
- Use the module to pass commands only (e.g., LoRa → UART → PCBA)
- Lighting logic is handled by the PCBA’s onboard MCU
- We provide Modbus UART protocol documentation
- Simply send commands like “turn on”, “dim to 50%” — no embedded code needed
✅ Example:
A Mexican customer used a LoRa module to relay cloud commands to PCBA, with no custom code.

The Question
Common FAQ
–This semi-finished solution is provided for this purpose.
–AC-DC circuit, relay switching circuit, ultra-long-life control circuit, dimming circuit, light sensor acquisition circuit, electrical metering circuit, power-off energy storage circuit, RTC circuit, etc.
–The communication module is only suitable for Modbus UART integration. For example:
The integration document states that if the semi-finished PCBA needs to turn off the lights, the command 1234 must be sent to it. The platform then sends the light-off command to the communication module. The communication module outputs 1234 to our PCBA as required, and the lights are turned off. Throughout this process, the communication module is merely a data forwarding hub.
–The customer selects the module, we design the module adapter board and integrate it into the complete device, the customer integrates and tests according to the documentation, and the product is complete. Throughout the entire process, the customer only needs to provide a software engineer to coordinate.
–Core software automation is a marketing slogan for customers who choose the peripheral integration solution. With this solution, customers need to write their own lighting code. Since they write it themselves, they have full control over it and can make design changes at any time based on their project needs.
