🚀 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
Modular Addressable LED Strip Controller – ESP32-based, WLED-compatible, Expandable
