• Description
• The SparkFun Lumenati 90R 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 90R board has been specifically designed to be daisy-chained with other Lumenati boards, thanks to the castellated edge connectors at each *** 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 **** 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 90R gets its name from the 90° angle it takes and the direction the signal and power flow. Combining four of the 90R 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 90R 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-indep***ent, 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 *** of additional hardware.
• Note:
• There are two solder jumpers on the back of the 90R 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.
