SMLIGHT A1-SLWF-09 | Modular ESP32 LED Controller with WLED Pre-installed

SMLIGHT | A1-SLWF-09 | Modular ESP32 LED Controller with WLED & USB-C PD

Take your lighting projects to a professional level with the SMLIGHT A1-SLWF-09. This powerful, modular LED controller is specially designed for controlling addressable (digital) LED strips in advanced smart home environments. Thanks to the powerful ESP32-D0WD-V3 processor with 16 MB of flash memory and the pre-installed WLED software, you can effortlessly connect your lighting to your central network to create impressive lighting effects and automations for all your lighting in the home.

Versatile Power Options: USB-C PD/QC, DC Plug & Fast Wire Terminals

The A1-SLWF-09 excels in ease of installation and power flexibility. The controller supports a wide input voltage from 5V to 24V DC via a traditional 5.5x2.1mm DC jack or via the screwless fast wire terminal. Unique to this controller is the smart USB-C port with Power Delivery (PD) and Quick Charge (QC) support. This allows you to power even a 12V LED strip directly via a suitable USB-C PD charger! The built-in MOSFET relay control (GPIO33) also provides a physical power supply shut-off to completely eliminate leakage current and standby consumption of your LED strips.

Dual-Channel Control with Level Shifters & Modular Add-ons

Thanks to the integrated hardware level shifters, the data signal from the ESP32 is converted noise-free into a pure 5V signal, preventing flickering LEDs and signal loss over longer distances. The controller comes standard with 2 hardware LED output channels (expandable via GPIOs) and features two physical control buttons and a DIY terminal for external buttons or an IR receiver. Furthermore, the A1-SLWF-09 can be modularly expanded with separately available expansion modules, such as a LAN8720 Ethernet module for a wired network, an IEEE 802.3af PoE module (5V 1.5-2A), or a high-quality ICS-43432 I²S digital MEMS microphone for sound-controlled WLED lighting effects and Home Assistant Voice Assistant functionality.

Ecosystems & Compatibility

• Home Assistant: Flawless, 100% local integration via the native WLED integration or via ESPHome. Can also be used as a Bluetooth Proxy (BTProxy) or as an external microphone for Home Assistant Voice. Also check out our Home Assistant category for suitable controllers and accessories.
• Homey Pro: Can be directly controlled on Homey Pro via the official WLED app or via local HTTP and MQTT commands.
• SmartThings: Can be connected via virtual devices, webhooks, or overarching automations from a connected Home Assistant instance.
• Tuya / Smart Life: Suitable for integration via local webhooks or cloud-to-cloud connections from your central smart home controller.

Pro-Tip from slimhuisje.nl: Use the A1-SLWF-09 as a combined WLED controller and as a Bluetooth Proxy (BTProxy) for Home Assistant. This way, you not only control your LED strip, but also immediately increase the range of all your Bluetooth door sensors and mope sensors on that floor!

Technical specifications

Frequently Asked Questions (FAQ)

Is the SMLIGHT A1-SLWF-09 ready to use out of the box?

Yes, the controller comes pre-installed with WLED firmware. Once you connect it to a suitable power supply and connect it to your Wi-Fi network, you can immediately control the LED strip via the user-friendly web interface.

What power options can I use for this controller?

You can power the A1-SLWF-09 in several ways: via the screwless fast wire terminals (5V-24V DC), the standard 5.5x2.1mm DC plug, a USB-C charger with Power Delivery (PD/QC for 5V or 12V), or via network power with the optionally available PoE module (5V 1.5-2A for 5V strips).

Can I install ESPHome on the A1-SLWF-09?

Absolutely! Thanks to the built-in USB/UART programmer with autoboot function, you can easily reflash the controller to ESPHome, Tasmota, or custom firmware via your USB-C cable without needing extra flashing tools or button combinations.

What add-on modules are available for this model?

SMLIGHT offers three optional expansion modules that can be connected via the available JST headers: a 10/100 Mbps Ethernet module (LAN8720), an IEEE 802.3af PoE module for network power, and a high-quality ICS-43432 I²S digital microphone module for sound-controlled lighting effects and voice control.

Are a power adapter, LED strip, or add-ons included with this item?

No, the package contains only the assembled SMLIGHT A1-SLWF-09 controller. An external DC power supply, USB-C cable, LED strip, and any add-on modules must be purchased separately.
