Connect a Teensy 3.2 to 4.1 to thousands of WS2812 LEDs using this OctoWS2811 adapter. Buffered outputs, impedance-matched resistors, and CAT6 RJ-45 connections ensure clean signals and easy cabling.

This adapter board connects Teensy 3.2 - Teensy 4.1 to thousands of WS2812-compatible LEDs using the OctoWS2811 Library.

The adapter features a 74HCT245 buffer chip and 100-ohm impedance-matching resistors. CAT6 Ethernet cable is used from this board to the LED strips. CAT6 cable is designed for very high bandwidth, minimal cross-talk between twisted pairs, and 100-ohm impedance, for a very high-quality signal. The RJ-45 network jacks allow your LED array to be easily disconnected from the electronics.

Teensy 3.x is added on top of the adapter using stacking header pins, or a header and socket pair if you wish to be able to remove the Teensy 3.x board. This adapter can also be used with the larger Teensy 3.5, 3.6, 4.1 boards using double insulator pins and sockets. Together, these are tall enough to allow the longer board with the SD socket to overhang the RJ-45 connectors.

To prepare the data cables, simply cut a CAT6 Ethernet cable in half and carefully strip away the outer jacket to expose long enough sections of the twisted pairs to reach all of your LED strips. Each twisted pair feeds the data input and ground of a single strip.

This adaptor board is designed to fit inside a CableGaurd 500 Coax Demarcation Enclosure (not yet available in the store). The CG-500 is a very durable enclosure meant for outdoor applications. The outside size is approximately 16.5cm by 20.3cm. Even though this is the smallest CableGaurd enclosure, there's plenty of room inside for even two OctoWS2811 adaptors.
