It connects Teensy 3.2 through 4.1 boards to thousands of WS2811, WS2812 or NeoPixel-compatible LEDs, with support for driving up to eight strips in parallel via the high-speed OctoWS2811 Library.The adapter acts as an active signal buffer, using a 74HCT245 buffer chip to boost the Teensy's 3.3V logic signals to the 5V level required by most LED strips. This helps provide reliable signalling for larger installations and longer cable runs.Dual RJ-45 Ethernet jacks work with onboard 100Ω impedance-matching resistors and standard CAT6 Ethernet cable for clean, high-bandwidth signal routing with minimal cross-talk. The RJ-45 connections also make LED arrays easy to connect and disconnect from the main controller.Teensy 3.2 and 4.0 boards can mount directly on top of the adapter using standard stacking headers or a header/socket pair. Larger Teensy 3.5, 3.6 and 4.1 boards are also compatible when raised with double-insulator pins and sockets so the board clears the RJ-45 connectors.This adapter is suited to art installations, stage props, light shows and other projects that need many addressable LEDs driven from a Teensy. **Product Type:** LED Driver Adapter ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDd8ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a829a9999ea42e304ffb5ba2ef5f8931922325a7/28372-octo28-shield-for-teensy-feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDecECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ed52d6d4ebe4f2a2b75291eaab56176ae227b3e4/28372-octo28-shield-for-teensy-front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDesECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--abf1cbc82768645c43c3e1726c9de1b650e0f8d4/28372-octo28-shield-for-teensy-back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDe8ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f748a9df584e98ed13c1b8ae1826a784dc4c21d0/28372-octo28-shield-for-teensy-scale.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDfMECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--65c38b9e0a9360af2c0173ac0e25c5e9fce3cf79/octo28_adaptor_3.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDfcECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--5df34cd57fde34084726c600f37212dac85b1af6/octo28_adaptor_8.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDfsECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1dba66a45062f933473d0d5d8bd124eed8d426fc/octo28_adaptor_6.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
