SF: SunFlower

SF has 65 WS2812B-2020 LEDs in a Fibonacci distribution on one circuit board. It has another board as light diffuser with a beautiful pattern to match the Fibonacci distribution of LEDs.

Both FPC connector and FPC cable make the connection with the adapter simple and easy. The adapter is made for Seeedstudio XIAO boards. If you choose the full package, there is no soldering and everything works out of the box.

The design with FPC also makes the extension easier. Several SF boards could be connected and extended with FPC cables and all are driven by one controller. Ask for longer FPC cable for extension along with your order.

If you have your own controller, the basic package is for you. If you do not bother to find a controller board, the full package is your bet.
