When operating, this controller manages addressable LED strips using WLED digital functionality. The device supports over 200 available WLED effects and offers segmented color control. It utilizes a built-in PDM microphone, which facilitates dynamic, beat-driven effects and music-sync capabilities. Connectivity is wireless, allowing compatibility with app control, Amazon Alexa, and Home Assistant.



Assembly features several protective details. The unit employs dual relays and fuses to deliver independent, per-channel safety for the installed LED strips. Powering the unit is flexible; it accepts input via a screw terminal block, a DC barrel jack, or a Type-C port. The hardware includes two red detachable 10A blade fuses, and the terminals feature lever-action quick-connection wire connectors for installation ease.



The maker included a black DIY expansion port on the unit. This port allows for the integration of additional components like buttons or PIR sensors. The unit has an IP20 rating, ensuring durability in its operating environment. Status indicators clearly show red when a fuse faults and green when a relay engages.



While the unit provides three ways to power the device, the maker specified that the Type-C input only supports 5V. This means that if a user needs to power higher voltage strips, they must utilize the DC jack or the V+/V- terminal, which presents an obvious power consideration for users selecting this controller.


How does the maker intend for users to utilize the 5-pin DIY terminal, since it lists specific pins like IO5, IO18, and IO33?

The choice to include per-channel protection using dual fuses and relays seems very sensible. It moves beyond simple device protection and offers critical safety for the LED strips themselves, which is a major benefit for large installations.

Given the DIY GPIO extension capabilities, the maker could improve the unit by integrating support for external dimming sensors. This would allow the controller to dynamically adjust brightness based on ambient light levels.

The maker has stated that a 5-pin DIY terminal is available and it is labeled with specific designations: 5V, GND, IO5, IO18, and IO33.
