The GL-C-016WL-D is the hardware revision of the GL-C-015WL-D. All performance specifications are identical — ESP32, 15A total output, built-in digital microphone, support for 800 ICs and all major single-wire addressable protocols. Two physical changes only: the Micro-B UART port has been replaced with USB Type-C, and the housing is orange instead of black.
Ships with WLED firmware pre-installed. Connect power, connect your addressable LED strip to GPIO16, join WiFi — live in under two minutes. No hub, no cloud, no account required. The USB Type-C UART port enables serial firmware flashing and debugging without disassembly — useful for custom WLED builds or ESPHome migrations.
The on-board regulator and MOSFET relay eliminate the need for a separate 5V USB power supply and cut strip current draw to zero when WLED is off.

Supported LED Strip Protocols
Supports all single-wire addressable (NeoPixel-style) protocols. Not compatible with analogue (non-addressable) LED strips.
| Protocol | Notes |
|---|---|
| WS2812B / WS2812 / WS2813 / WS2815 | Most common — 5V or 12V variants |
| SK6812 (RGBW / RGBNW) | 4-channel including white |
| WS2811 | 12V addressable, 3-LED pixel groups |
| SM16703P | Compatible single-wire protocol |
| TM1814 | RGBW, 12V |
Home Assistant Integration
WLED integrates with Home Assistant via the native WLED integration — no YAML, no custom component. Once on your network, Home Assistant auto-discovers the controller and creates a light entity with full brightness, colour, and effect control.
Advanced users can flash ESPHome via the USB Type-C UART port. Connect a USB-C cable, hold the boot button while powering on, and flash via the ESPHome CLI or dashboard. The Type-C connector provides better physical durability than Micro-B for repeated firmware iterations.
Supported control methods: WLED web UI · WLED iOS/Android app · Home Assistant (WLED integration) · MQTT · HTTP JSON API · E1.31/Art-Net DMX (network)
Wiring — Addressable LED Strip
For a standard single-wire addressable strip (e.g. WS2812B at 5V or 12V):
| Terminal / Pin | Connect to |
|---|---|
| V+ (input) | PSU positive (5V, 12V, or 24V DC) |
| V− (input) | PSU negative / ground |
| GPIO16 (data) | Strip DIN (data in) — primary channel |
| Strip GND | Shared PSU ground (run a GND wire alongside data) |
| GPIO2 | Optional second strip DIN — secondary channel |
Always share a common ground between the PSU, controller, and LED strip. For runs over 2–3m, inject power directly at the strip and keep data and ground wires short. Use a constant-voltage PSU rated at least 20% above total strip load.
FAQ
What is the difference between GL-C-016WL-D and GL-C-015WL-D?
Physical differences only: the GL-C-016WL-D has a USB Type-C UART port (versus Micro-B on the 015WL-D) and orange housing. ESP32, 15A output, microphone, GPIO pinout, strip compatibility, and WLED firmware are identical. Choose Type-C if you prefer not to keep a Micro-B cable around.
Does this work without a hub?
Yes — WLED runs fully local over WiFi. No Zigbee coordinator, no Philips Hue bridge, and no cloud account required. Control via the WLED web UI or app directly. Home Assistant integration is optional.
Can I flash ESPHome using the USB Type-C port?
Yes. Connect a standard USB-C cable to a computer, hold the boot button while powering on, and flash ESPHome via the CLI or dashboard. The Type-C connection also works for serial debugging in the ESPHome log viewer. Note that standard USB-C data cables work here — the port is wired for USB serial, not power delivery.
Does the microphone work out of the box?
Yes — the AudioReactive usermod is pre-enabled in the WLED firmware. Apply any AudioReactive effect preset and the mic is active immediately. No additional configuration required for basic music sync.
