SLWF-11 — our new compact WLED LED controller
Say hello to the SLWF-11 — a compact, fully-equipped WLED controller: four data lines, screw terminal, DC barrel jack, built-in USB/UART converter, IR receiver, and 5–24 V strip support — in the smallest footprint, at full SMLIGHT quality. Coming to our distributors very soon.

We're excited to introduce the newest member of our LED controller family: the SLWF-11 — a compact addressable-LED controller built around the ESP8266 and powered by WLED, pre-flashed and ready to light up your first strip minutes after unboxing.
Why you'll love it
- Fully equipped, out of the box. Nothing stripped out: four data lines, a screw terminal, a DC barrel jack and USB Type-C, a built-in USB/UART converter, an IR receiver, and support for 5–24 V strips.
- The compact footprint — a truly tiny board that tucks in behind the strip, inside an aluminium channel, or anywhere space is tight.
- Extremely good quality — small and inexpensive doesn't mean cheap: the SLWF-11 is built and tested to the same standard as every SMLIGHT device.

Ready out of the box
Every SLWF-11 ships with WLED pre-installed. Power it up, join its Wi-Fi setup network, pick your home network — and you're painting light: 100+ effects, 16.5 million colours, native iOS & Android apps, and effortless syncing across multiple controllers. Updates arrive over the air, or over USB Type-C when you prefer a cable.
Prefer a different stack? The SLWF-11 also runs ESPHome, and it's right at home in Home Assistant.
One board, everything included
- Level-shifted Data + Clock outputs at clean 5 V logic — drive 3-wire strips (WS2812B-class) and 4-wire clocked strips alike; strips with 5 V-tolerant data inputs such as WS2815 work too.
- Built-in IR receiver (38 kHz) — dim, switch effects and power on or off from the couch.
- On-board control button plus two status LEDs.
- Built-in USB-to-UART programmer — flash firmware straight over Type-C, no external adapter needed.
- DIY expansion header — spare GPIOs, an ADC input, 3.3 V and GND for your own sensors and mods.

Power it your way
Three inputs, one board: USB Type-C for the bench, a 5.5 × 2.1 mm DC barrel jack for standard adapters, and a screw terminal for permanent installs and higher-current supplies — use whichever fits the job (one source at a time, as always). Strips from 5 V to 24 V are supported.
SLWF-11 or SLWF-03?
Both are SMLIGHT WLED controllers — pick by how you like your light:
| SLWF-11 | SLWF-03 | |
|---|---|---|
| Wi-Fi SoC | ESP8266 | ESP32 |
| Microphone | None | built-in digital microphone |
| Sound-reactive effects | Not supported | out of the box |
If you want sound-reactive lighting, the SLWF-03 is the one to grab: it has a built-in microphone, which the SLWF-11 does not. For everything else — clean, reliable strip control with flexible power at the friendliest price — the SLWF-11 keeps it simple.
