What is it?

This is an IO expansion board for the Teensy (3.2-4.0) running OctoWS2811 library. It's designed to make any WS28xx LED strip based project super easy to hook up with no soldering required. All you need to get started is

• Teensy with pins
• LEDoctopus board
• WS281x LED strips (up to 8)
• 5V power supply with barrel connector
• wire stripper
• 2.5mm flat head screen driver

Why did you make it?

Existing interconnect board for the Teensy is a pain to actually hook up to LED strips. Soldering is required and grounding scheme is really a pain to manage. Some boards that have individual breakout connectors for strips are large and require specialized connectors to power. I wanted to build a compact expansion board that makes interconnects super simple for LED projects but also have expansion capabilities that makes it useful to include other sensor inputs or outputs.

What makes it special?

Teensy connection does not require soldering so you can unplug the Teensy for other projects. Included screw type terminal blocks are ideal for providing both data and power directly to up to 8x LED strips. Debugging is also made simpler by the easy connect/disconnect of the terminal blocks. 5V power (up to 5A) is provided via the standardized barrel connector to all strips as well as to the Teensy (if USB power is not connected)

For high power applications, footprint for connector rated for up to 45A total is available on the board. Please note that you should NEVER plug in more than one power supply to the board at once.

This board also works great for generic Teensy DIY application since multiple outputs along with power and ground are easily accessible via the terminal block connectors. And many of the extra IO's for the Teensy are pinned out to the 0.1'' headers on the board.
