HWYD WS2811 BRIDGE v3

Prototyping with LED's and the Rasperry PI

This Raspberry Pi shield is designed with LED prototyping in mind. We love building with Neopixels and needed a tool that was easy to use. attaches to the GPIO pins of your RPi and acts as a WS281X Bridge between your dreams and the LED's of your choice. The shield allows us to streamline our led ideas without the need of a breadboard, cobbler setup and extra wires.

A note for v3 users: we've updated the pinout order on v3 to GND, PWR, DIN.

Features

• Supports Raspbbery Pi A, B/B+, 2, 3, Zero and Zero W!
• Works with any WS2811 / WS2812 LED's and Neopixels (strips too)
• 3 pin Molex slots for easily swapping out your LED's
• 100uf capacitor to protect against surges while powering
• Based off 74hCT125N
• Inspired by adafruit Neopixels and Fadecandy.

BUILD GUIDE

If you purchase our board unassembled. Please follow the guide below. Note that v2 and v3 boards have different pinouts for the LED strips; everything else is the same.

We chose Raspberry Pi for it's speed, networking capabilities, threading etc. Also we like the flexbility Python offers for web and data minded projects.

STEP 1: PARTS LIST

* HWYD Board
* Raspberry Pi
* 3pin Molex
* Power Jack
* IC
* IC Socket
* 2x20 Headers
* 100uF Capacitor

STEP 2: SOLDER

Solder it up. This version of the board has 5 parts and should take 
10-15 minute to complete.

STEP 3: ATTACH

V2 boards

DIN, POWER, GROUND

V3 boards

GND, PWR, DIN

INSTALLING DRIVERS

We are using the rpi_ws281 library from jgarff. You can find a more detailed version of the driver installation guide from adafruit.

STEP 1: Update your Pi

sudo apt-get update
sudo apt-get install build-essential python-dev git scons swig

STEP 2: Download the rpi_ws281 library

git clone https://github.com/jgarff/rpi_ws281x.git
cd rpi_ws281x
scons

STEP 3: Install

cd python
sudo python setup.py install

STEP 4: Run an example

cd python/examples
sudo python strandtest.py
