{"product_id":"sparkfun-smartled-shield-teensy-4","title":"SparkFun SmartLED Shield - Teensy 4","description":"\u003cp\u003eThe SmartLED Shield enables the Teensy 4 to drive high-quality graphics to HUB75 RGB LED panels, with 36-bit color and 240 Hz refresh rate across large panels (e.g. 128x64 pixels). A Teensy 4.0 or Teensy 4.1 with pins fits into the socket on the shield, and the shield can attach directly to the HUB75 panel or through a ribbon cable. The SmartMatrix library for Arduino makes it easy to draw basic graphics, create scrolling and static text, draw beautiful patterns using FastLED, and play animated GIFs on the panel. \u003ca href=\"https:\/\/www.crowdsupply.com\/pixelmatix\/smartled-shield-for-teensy-4#example-code\"\u003eExample code\u003c\/a\u003e is provided so you can get started as quickly as possible. The Shield and library use special features and peripherals of the Teensy 4 processor to send graphics data to your display with minimal CPU usage, so you can use the processor to do other tasks in parallel such as SPI communication, file decoding, or complex rendering.\u003c\/p\u003e \u003cp\u003eUsing SmartLED Shield with SmartMatrix library and the Teensy 4 is the easiest way to drive high-quality and high pixel count graphics to RGB LED panels with a microcontroller. Use a simple API to tell the library what to draw on the screen, and the library takes care of refreshing in the background. Advanced features like these are enabled automatically:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e36-bit Color Refresh - See the full color range in the image or pattern you're displaying, with no noticeable brightness steps when dimming pixels down to black. Up to 48-bit color refresh is available.\u003c\/li\u003e \u003cli\u003eColor (Gamma) Correction - Your source graphics are probably 24-bit color, but SmartMatrix library applies automatic color correction so they have good contrast, smooth gradients, and don't look washed out.\u003c\/li\u003e \u003cli\u003eGlobal Brightness Control - When you don't need the full brightness of the LED panel, lower the brightness without having to sacrifice color depth of your graphics.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThe shield is easy to assemble and connect to a panel, and there�s no soldering required beyond adding pins to the Teensy.
