Its HDR SK9822-2020 are capable of being driven much faster for higher frame-rates, and with better color depth, especially at lower brightnesses. This makes it perfect for wearables that are powered with lithium batteries. It is similar to the LED PCB used in [Lux Lavalier](https://lectronz.com/products/lux-lavalier-wearable-light-art-pendant), but listed separately here for use in other projects. It has four mounting hole touch pads for use with the [SAMD21 QT Py by Adafruit](https://www.adafruit.com/product/4600). I have created several LED art pieces in Fibonacci patterns. They are all very labor intensive to create, and so are fairly expensive and limited in quantity. I wanted to come up with a Fibonacci layout that was at least slightly easier to create, and therefore more affordable. I have RGB LEDs in just about every form they come: strips, strings, rings, discs, etc. The LEDs on most discs are arranged in very regular rings. Fibonacci64 is different. The LEDs are arranged in a Fibonacci distribution. The makes the layout very organic and seemingly messy. But with the proper animation, spiral patterns emerge with spectacular results. The SK9822-2020 each only consume a maximum of 20mA, and that's at 100% brightness, solid white color. That's only 1,280 mA for all 64 combined. They are still very bright, and I usually only run them at about 25% brightness. They're perfect for wearables, powered with lithium batteries. It has solder pads on the back that match the pinout of the [QT Py by Adafruit](https://www.adafruit.com/?q=qt+py), or [XIAO by Seeed](https://www.seeedstudio.com/catalogsearch/result/?q=xiao). It also has solder pads on the back that match the pinout of the amazing [Pixelblaze V3 Pico](https://shop.electromage.com/products/pixelblaze-v3-pico-tiny-wifi-led-controller) by ElectroMage. But note that the touch pads are not supported by Pixelblaze. It can be used by any microcontroller via the 5V, GND, and Data In pins. It also has a Data Out pad, for connecting more LEDs on the same data pin. The four mounting holes are surrounded by capacitive touch compatible pads. They're connected to the A0-A3 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins. **Case Options** The open case is built with 3mm black LED acrylic diffuser and back plates, black nylon M2 standoffs, and M2 screws. Available as kit or fully-assembled. **Specifications** - Size: 1.57 x 1.57 x .063 inch (40 x 40 x 1.6 mm) - 2 layer printed circuit board - FR4 substrate - Black SMOBC (solder mask over bare copper) - HASL (Hot Air Solder Leveling) - Designed in the US by Evil Genius Labs **Parts** Options available to purchase for additional amount: - Diffuser: 3mm black LED acrylic 42mm circle. - Open Case Kit: diffuser, back plate with wall mounting hole, M2 black nylon standoffs, M2 black metal screws. - Fully Assembled: diffuser, open case, and assembled [QT Py by Adafruit](https://www.adafruit.com/product/4600) controller. The "Fully Assembled" option requires, but does not include, a USB-C cable and power source (USB port, AC power adapter, battery pack, etc). If the "Fully Assembled" option is not chosen, these parts are **not included**, but are required to assemble and use: - Microcontroller (Arduino, ESP8266, ESP32, etc) - Wires, connectors, crimp tool, etc. - Soldering iron, solder, etc. Parts I used in my builds: - [QT Py by Adafruit](https://www.adafruit.com/product/4600) - [Chemcast Black LED Acrylic](https://www.tapplastics.com/product/plastics/cut_to_size_plastic/black_led_sheet/668) [Assembly Instructions](https://www.evilgeniuslabs.org/fibonacci64-micro#assembly-instructions) ## Shipping policy * Orders are normally shipped within one business day. * Emails are sent with tracking numbers once orders ship. * Orders ship from the US. * Depending on the destination, orders normally arrive within a few days in the US, and up to several weeks internationally.
