The SmartLED Shield (V4) provides a simple, solder-free way to connect a Teensy 3.2, Teensy 3.5, or Teensy 3.6 to HUB75 RGB LED Matrix Panels. Just plug in your Teensy, connect your panel, and start displaying graphics, patterns, or animated GIFs using the SmartMatrix Library.
The shield includes 5V level shifters for reliable panel compatibility, a HUB75 connector that accepts direct panel connection or ribbon cables, and expansion headers for prototyping with the remaining Teensy I/O pins.
Key Features
- Fully Assembled – No soldering required (beyond adding pins to your Teensy)
- HUB75 Connector – Connects directly to RGB LED matrix panels or via ribbon cable
- 5V Level Shifters – Pre-soldered for reliable compatibility with 5V panels
- DotStar/APA102 Support – Drive DotStar LEDs in parallel with the LED panel via 4-pin JST SM connector
- Expansion Headers – Access remaining Teensy I/O pins for prototyping
- Removable Teensy – Easily insert and remove your Teensy board
Ideal For
- RGB LED matrix display projects
- Animated GIF displays from microSD card
- Interactive signage and art installations
- Prototyping with Teensy and LED panels
Package Contents
- 1× SmartLED Shield V4 (fully assembled)

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- HUB75
- HUB75 is a common connector and signalling standard used by many RGB LED matrix panels. If a controller supports HUB75, it can plug into compatible matrix panels without custom wiring, but you still need to match the panel size and power requirements.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
