![enter image description here][1] ![enter image description here][2] ![enter image description here][3] **DESCRIPTION** The LED Strip Driver with 4-pin Grove interface provides easy connectivity to your standard Arduino device or Seeed Stalker. It can help you control the luminance of a single-color LED strip, as well as the color and the luminance of an RGB LED strip through Arduino or Seeeduino. It has 2 terminals and 2 Grove interfaces. The power for the LED strip comes in through the 2-pin terminal. And the LED controlling voltages output through the 4-pin terminal. The 2 Grove interfaces are respectively screen-printed “IN” (for controlling data input) and “OUT” (for controlling data shared with the next strip driver). It can drive an LED strip 1 to 2 meters long with 9 V, while 1 to 5 meters long with 12 V. The driver in conjunction with the colorful LED strips can add a wonderful effect to indoor or outdoor usages. ![enter image description here][4] **Features** Grove compatible interface Can be cascaded for a larger display Best results achieved with LED strips 5 meters long or shorter Outputs PWM signals 256 gray-levels are adjustable via programming Arduino and MEGA compatible Screw Terminals (power input and control signal output interface) **Documents** Please visit our [wiki][5] page for more info about this product.
