## Description

Big LED strips need more current than a microcontroller can supply, and a 12V strip needs more voltage than it can tolerate. This compact carrier solves both at once, sitting between a Seeed Studio XIAO and up to 3A of 5V or 2A of 12V addressable LEDs.

Power comes in through a standard 5.5 x 2.1mm DC barrel jack or bare 12V wire, and leaves through a 4-pin 3.81mm screw terminal carrying 12V, 5V, A0 and GND - so the strip connects with a screwdriver rather than a soldering iron. Onboard regulation, a power switch and protection against overcurrent, overvoltage, overtemperature and short circuits mean the install can be left running unattended.

Pair it with a XIAO ESP32-C3, ESP32-S3 or ESP32-C6 and the board becomes a smart lighting controller: flash WLED for app-driven colour, brightness and custom animations, or run ESPHome to expose the lights to Home Assistant for automation and voice control. The onboard Grove I2C connector adds any of Seeed's 400+ Grove modules, so motion, ambient light or temperature can drive the effects.

### Features

- Drives both 5V/3A and 12V/2A strips from one board, thanks to built-in power regulation - no separate buck converter or level shifter needed
- Works with single-colour LEDs and addressable RGB types including WS2811, WS2812(B), WS2813, WS2815 and SK6812, plus other 1-wire protocol LEDs
- Turns a XIAO ESP32 board into a WLED or ESPHome node, giving you phone control and Home Assistant automation without writing firmware from scratch
- Grove I2C connector (D4/D5) lets you add sensors from the 400+ module Grove ecosystem for reactive, interactive lighting
- 4-pin 3.81mm screw terminal makes strip connection tool-simple and serviceable - swap strips without desoldering
- Overcurrent, overvoltage, overtemperature and short-circuit protection guard both the strip and the XIAO during long installs
- Breaks out SPI, UART and two digital pins, plus a user button on D3 and a power switch, for expansion beyond lighting
- Compact 63 x 30 x 14.4mm footprint (with a XIAO fitted) tucks behind a diffuser or into a channel
- Official Seeed Studio accessory, designed around the XIAO form factor - guaranteed mechanical and pinout fit
 
### Specifications

 | **Supported LEDs** | Single-colour LEDs; addressable RGB (WS2811, WS2812, WS2812B, WS2813, WS2815, SK6812); other 1-wire protocol LEDs |
|---|---|
| **LED connector** | 4-pin 3.81mm screw terminal block (12V, 5V, A0, GND) |
| **Power input** | DC 12V/2A via 5.5 x 2.1 x 10mm barrel jack, or direct DC 12V wire |
| **LED power output** | DC 12V or DC 5V |
| **Maximum operating current** | 2A at 12V, 3A at 5V |
| **Onboard** | Power switch x1, Grove I2C connector x1 (D4/D5), user button x1 (D3), power LED x1 |
| **User pin header** | SPI x1, UART x1, digital x2 |
| **Microcontroller compatibility** | All Seeed Studio XIAO boards. Smart features (WLED, ESPHome) require a XIAO ESP32 series board |
