Getting Started with the SmartLED Shield for Teensy
The PixelMatix SmartLED shield for Teensy makes it easy to connect to RGB LED matrix panels! The shield makes it easy to connect to the 16 pins required to drive the display, connects an external 5V supply to power the display and Teensy, and brings out the Teensy’s free signals to a convenient header.
In this tutorial, we will explore a some of the examples provided with the SmartLED shield using different RGB LED matrix panel sizes.
To follow along with this tutorial, you will need the following materials. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
RGB LED Matrix Panel
You will need a panel. The following has been tested to work with the examples provided.
- 1:16 with 32 rows
- 1:8 with 16 rows
- 1:32 with 64 rows
For example, if you are trying to use a 32x32 panel with a 1:8 scan rate, it may not display as expected.
To control the panel using the SmartLED shield, you will need a Teensy. You can use a Teensy 4.0 but you would need to make sure that you are using the appropriate SmartLED Shield version or adapter.
You will also need a 5V power supply. A 5V wall adapter and barrel jack adapter is the easiest way to connect power to the panel and Teensy. However, there are other methods depending on how you are powering the panel.
Depending on your setup and how you are controlling the panel, you may need these additional components.
Depending on your setup, you may need pliers, a soldering iron, solder, and general soldering accessories.
