SMLIGHT A1-SLWF‑09

What you can do with A1-SLWF-09, in a nutshell: You start with a base model device, which has the following characteristics:

Modular: The user can install Ethernet, POE, and Digital microphone modules.
Slim and very 'hiding' device. We intentionally did not put any marks on top of the enclosure, so users can install them on a white wall, and they will not catch a lot of attention.
Fast wire terminal - just one click - and your LED strip or power strip is connected, no screws.
It can be powered by Type-C PD/QC (only with smart technology) - because the device has a switch and can choose either 5V or 12V! Yes, you can power a 12V LED strip via Type-C (requires PD / QC power supply). Cool, isn't it?
It can be powered by PoE. We recommend limiting to limit by 1.5-2A. Only 5V strip (WS2812, etc).
Relay: It has a physical MOSFET relay (GPIO33). Also, you can use the available wire terminal to bypass the Relay.
Has two outputs to Addressable LED strips (with level-shifters).
Two buttons to control the device
DIY screw terminal header
