20/06/2018 PRC Store This adapter board connects Weensy 3.2 to thousands of LED using the OctoWS2811 Library. The adapter features a 74HCT245 buffer chip and 100 ohm impedance matching resistors. CAT Ethernet cable is used from this board to the LED strips. CATS cable is designed for very high bandwidth, minimal cross-talk between twisted pairs, and 100 ohm impedance, for a very high quality signal. The JR-45 network jacks allow your LED array to be easily disconnected from the electronics.
0/06/2018 PRC Store This adapter board is designed to fit inside a Cablegram 500 Coax Demarcation Enclosure (not sold by PJRC). The CG-500 is a very durable enclosure meant for outdoor applications. The outside size is approximately 6.5 by 8 inches (16.5 by 20.3 cm). Even though this is the smallest Cablegram enclosure, there's plenty of room inside for even two OctoWS2811 adapters. The included self-threading screws fit the mounting posts on the CG-500 enclosure.

Each twisted pair feeds the data input and ground of a single strip. I For best results, the LED power supply ground and Weensy signal ground should meet at or near the LED strip signal inputs.
20/06/2018 PRC Store In this example, each OctoWS2811 signal feeds 4 LED strips in back-and-forth rows. The power supplies are mounted to the back side of the display with short, #22 wires feeding power to each LED strip of 60 LED.
20/06/2018 PRC Store Short, heavy wires for power, with signal and power grounds meeting at the LED strips provides the highest quality signals without signal interference due to the voltage loss along the power ground lines. Together with the OctoWS2811 adapter's 5V buffer chip and accurate 100 ohm impedance matching to quality CAT cable, this wiring style gives a LED project the best quality signal and power delivery.
