The SparkFun Lumenati 90L is a small quarter-circle board equipped with three APA102C LEDs and a single mounting position that has been designed to give your projects an edge in their lighting capacity. The 90L 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 90L gets its name from the 90° angle it takes and the direction the signal and power flows. Combining four of the 90L boards creates a 12 LED ring with enough space in the center for a Lumenati 8-pack board. If you want to create more than just a small ring, you can also solder on 8-stick boards to the 90L 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 90L 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 90L是一個小四分之一圓的板，配有三個APA102C LED和單個安裝位置，旨在為您的項目提供照明能力的優勢。 90L電路板專門設計為與其他Lumenati闆卡式連接，這得益於每端的端口連接器，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 90L的名稱從90°角度和信號和功率的流向。組合四個90L電路板在Lumenati 8包裝板上創建一個12個LED環，中心有足夠的空間。如果您想創建的不僅僅是一個小戒指，還可以在8-stick板上焊接到90L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，但優點在於與LED的通信變得有點時序無關，允許您直接從Raspberry Pi或其他單板計算機運行它們，通常不允許長時間精確定時的數據流，無需使用額外的硬件。
注意：在90L標記的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，以防您在不想要時鐘的情況下進行閉環設計數據從你最後一個LED干擾時鐘和數據到你的第一個。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。
