The A-SLWF-11 is a compact addressable-LED strip controller built around the ESP8266 Wi-Fi SoC and powered by WLED open-source firmware. It is designed for simple, reliable control of WS2812B-class and clocked LED strips, with flexible power input and a small set of built-in controls.
The device arrives pre-flashed with WLED and works immediately over Wi-Fi. It can also run other ESP8266 firmwares such as ESPHome, and integrates with Home Assistant.

Key Features
- ESP8266-based WLED controller — ideal for small-to-medium addressable installations.
- Three power inputs: USB Type-C, DC barrel jack and screw terminal.
- Two LED signal outputs — Data and Clock — delivered at a clean 5 V logic level through an on-board level shifter, so both 3-wire (Data-only) and 4-wire (Data + Clock) strips are supported.
- Built-in IR receiver for infrared remote control.
- On-board push button for manual control (also used to enter flash mode).
- Two on-board status LEDs.
- Built-in USB-to-UART programmer — flash directly over USB, no external adapter.
- DIY expansion header breaking out spare GPIOs, the ADC input, 3.3 V and GND.
- Full WLED compatibility; ESPHome and Home Assistant friendly.
How it differs from the A1-SLWF-03 The SLWF-03 is an ESP32 controller with a built-in digital microphone. The A-SLWF-11 is an ESP8266 controller with no built-in microphone. Sound-reactive effects on the A-SLWF-11 require an external analog microphone wired to the ADC pin on the DIY header.
