The SparkFun Lumenati 8-stick is a small board equipped with eight APA102C LEDs in a row and two mounting positions, that has been designed to give your projects an edge in their lighting capacity. The 8-stick board has been specifically designed to be daisy-chained with other Lumenati boards, thanks to the castellated edge connectors at each end allowing for multiple design options and formations. Additionally, we have labeled the APA102C LEDs on each board with numbers indicating their position in the sequence to help you write code more easily. We especially love using the Lumenati boards to give our flying race drones a bit of style and panache.
The Lumenati 8-stick can also be combined with the 90R and 90L boards to create outlines of different shapes and sizes.
The APA102C addressable LEDs operate on +5V power input, as well as 0–5V logic levels for clock and data, and employ a 2-wire communication protocol consisting of a clock line and a data line. While this requires one more wire than standard WS2812B LEDs, the advantage is that the communication with the LEDs becomes somewhat timing-independent, allowing you to run these directly off of a Raspberry Pi or other single-board computer that doesn’t normally allow for a long, precisely timed data stream without the use of additional hardware.
Note: There are two solder jumpers on the back of the 8-stick labeled CO and DO (clock out and data out) that can be cut to interrupt those signals in case you make a closed-loop design where you don’t want the clock and data from your last LED to interfere with the clock and data to your first. It is critical that you cut the traces in the jumpers of the last board in the loop before you power up your LEDs if you’ve put together a continuous loop of Lumenati boards. Otherwise, it is likely that you’ll burn out a couple of LEDs.

SparkFun Lumenati 8棒是一個小型板，配有八個APA102C LED連續兩個安裝位置，旨在讓您的項目在其照明能力方面處於領先地位。 8針板已經專門設計為與其他Lumenati闆卡式連接，由於每個端部的雉腸邊緣連接器允許多種設計選項和結構。另外，我們已經在每個電路板上標上了APA102C LED，其數字表示其順序中的位置，以幫助您更輕鬆地編寫代碼。我們特別喜歡使用Lumenati板，給我們的飛行無人機有一點風格和panache。
Lumenati 8棒還可以與90R和90L板組合，以創建不同形狀和尺寸的輪廓。
APA102C可尋址LED工作在+ 5V電源輸入以及時鐘和數據的0-5V邏輯電平，並採用由時鐘線和數據線組成的2線通信協議。雖然這需要比標準WS2812B LED更多的電線，但其優點在於與LED的通信變得有些時序無關，允許您直接從Raspberry Pi或其他通常不允許的單板計算機一個長時間精確定時的數據流，而不使用額外的硬件。
注意： 8針標有CO和DO（時鐘輸出和數據輸出）的背面有兩個焊接跳線，可以剪切以中斷這些信號，以防您在不想要的情況下進行閉環設計時鐘和數據從您的最後一個LED干擾時鐘和數據到您的第一個。如果您將Lumenati板連續循環，則在啟動LED之前，切斷循環中最後一塊板跳線的痕跡至關重要 。否則，很可能會燒掉幾個LED。
