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)
- 1× DotStar/APA102 connection cable
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microSD card
- A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- 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.
