Product information "Adafruit SmartMatrix SmartLED Shield for Teensy 4"
The SmartLED Shield offers you an easy way to use a Teensy 4 or a Teensy 4.1 with one of our RGB LED matrix panels. With the sample sketches included in the SmartMatrix library, you can quickly start displaying graphics, patterns or even animated GIFs from a microSD card on your panel.
The SmartMatrix library for Arduino makes it easy to draw basic graphics, create scrolling text and static text, draw beautiful patterns with FastLED and play animated GIFs on the panel. Sample code is included to get you started as quickly as possible. The shield and library utilise special functions and peripherals of the Teensy 4 processor to send graphics data to your display with minimal CPU load, allowing you to use the processor in parallel for other tasks such as SPI communication, file decoding or complex rendering.
Using SmartLED Shield with the SmartMatrix library and the Teensy 4 is the easiest way to drive high quality, high pixel count graphics on RGB LED panels with a microcontroller. Use a simple API to tell the library what to draw on the screen and the library will take care of updating it in the background. Advanced features like these are automatically enabled:
- 36-bit colour refresh - See the full colour range of the image or pattern you're displaying, with no noticeable brightness steps as you fade from pixels to black. Up to 48-bit colour refresh is available.
- Colour Correction (Gamma) - Your source graphics are probably 24-bit colour, but the SmartMatrix library applies automatic colour correction so they have good contrast and smooth gradients and don't look washed out.
- Global brightness control - If you don't need the full brightness of the LED panel, lower the brightness without sacrificing the colour depth of your graphics.
Features
- Ease-of-use
- SmartLED Shield is fully assembled. If your Teensy has pins, then no soldering is required.
- Teensy can be easily inserted into and removed from the shield.
- SmartMatrix library for Arduino provides a simple development platform, along with others such as FastLED.
- Sample code is included for a quick start.
- Flexibility
- Controls displays up to 9k pixels (e.g. 96 x 96) with high quality settings, and even larger displays with reduced quality settings.
- Signals on the long edges of the Teensy are brought out in extension rows for easy prototyping.
- The 4-pin JST-SM connector can be used to power the Teensy separately from the USB port.
- Optional control of DotStar/APA102-compatible LEDs with the integrated 5 volt buffers and the 4-pin JST-SM connector. A suitable JST-SM cable is included in the scope of delivery.
- Panels can be connected in series to create large, bright, high-resolution displays.
- Drives all 14 signals of the HUB75 panels via 5V buffered outputs, using only 9 GPIO pins of the Teensy 4.0 or 4.1.
- Quality
- Offers a refresh rate of up to 240 Hz.
- Up to 48-bit colour reproduction is available.
- Colour correction (gamma) and global brightness control enable a high degree of visual quality control.

Adafruit: The expert for open source hardware
For more than ten years, programmers and tinkerers have benefited from the expertise of the Adafruit brand. Whether for beginners or proven experts, Adafruit has the right hardware components ready for your next IoT project.
Light comes into the dark with Adafruit NeoPixel
One extremely popular product line from the company's broad portfolio is Adafruit NeoPixel. These nifty LED components come in a wide variety of designs and color temperatures. NeoPixel modules are available, for example, in the form of a practical stick with five intelligent LEDs in red, green and blue (RGB) or in white (W), as a shield with 40 eye-saving RGBW LEDs in which all pixels are individually addressable, and as a jewel with seven RGBW LEDs that can be controlled with 8-bit PWM per channel.
Especially popular is the Adafruit NeoPixel Ring with 16 ultra-bright, intelligent RGB LEDs including integrated drivers, which you only need a single microcontroller to control. The trick is that the Adafruit NeoPixel rings form a chain, so to speak: You couple the output pin of one with the input pin of the other.
With the Adafruit NeoPixel products you can realize a wide variety of projects - there are virtually no limits to your creativity. With the help of an Arduino, a jumper cable and the appropriate software, you can control a NeoPixel ring individually and light up the small LEDs as you wish - either individually or in a specific combination. This way, you can also create your own Vu meter with the versatile LED components. Practical: To make programming Adafruit NeoPixel easier, Adafruit provides an Arduino library as well as a Python library.
Adafruit Feather Boards: Powerful hardware in a compact format
With Adafruit Feather, the hardware specialist from the States also has various powerful development boards in its range, which are essentially equivalent to an Arduino in terms of function. All of these boards are equipped with similar features; among other things, the pin assignment is the same and there are also many parallels when it comes to the microcontrollers and the battery charging properties. In addition, you can also find Feather boards with special devices like Bluetooth, Wi-Fi and cellular network connectivity as well as boards with microSD slot in Adafruit's product range. The name "Feather" is no coincidence: The boards are also characterized by being particularly compact and, above all, lightweight.
The range of top-class product highlights is wide: The STM32F405 Feather, for example, is the fastest CircuitPython board from Adafruit with an outstanding 168 MHz and meets the highest demands. It is equipped with a STEMMA QT / Qwiic port at the end, which makes it easy to connect to I2C sensors. The Adafruit Feather nRF52840 Express, on the other hand, shines with Bluetooth Low Energy and can also be used with CircuitPython thanks to native USB support.
Another important part of Adafruit's portfolio are the FeatherWings. With these expansion modules, you can also include components such as a display or a motor driver in your IoT project. The FeatherWing Proto is a proven classic in Adafruit's portfolio. This is ideally suited as a prototyping add-on for all Feather boards. The Adafruit FeatherWing Wing Tripler Mini Kit, on the other hand, is ideal if you want to connect a Feather to two other FeatherWings at the same time.
With the Adafruit MIDI FeatherWing Kit you get a music capable FeatherWing, thanks to which you can equip your Feather with MIDI input and output jacks. And with the Adafruit FeatherWing OLED you can easily add a small OLED display to your Feather board - no soldering required.
Adafruit: What's behind the brand
As an expert in open-source hardware, Adafruit has long since established itself in the electronics industry. The company was founded in 2005 by Limor Fried. At the time, the talented and innovative electrical engineer was still a student at the renowned Massachusetts Institute of Technology (MIT). To this day, Fried is CEO of the electronics giant, which is now headquartered in New York. The company's name also goes back to its founder: Fried was once known on the World Wide Web by the nickname "Ladyada" - a tribute to the famous IT pioneer Ada Lovelace.
Adafruit says it is committed to getting more people excited about technology and science - and thanks to its first-class products, the hardware expert from the USA is sure to succeed!
