Grove – LED Strip Driver
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 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).
- Grove - LED Strip Driver V1.1：
- SI5904 is used to level translation.
78M05 is a Voltage Regulator, the output voltage is 5V.
Grove - LED Strip Driver V1.2:
replace SI5904 with two 2N7002.
- The package of 100nF capacitors is 0603, not 0402.
- 3.3K discrete resistors change to exclusion.
