microcontroller Crowd Supply LED SmartLED Shield for Teensy 4 HUB75 RGB matrix panels

Want to add a lot of LEDs to your Arduino project? HUB75 RGB panels are a good choice. Worried about the quality of the graphics? Lucky you! SmartLED Shield for Teensy 4 can drive high quality graphics to HUB75 RGB matrix panels. 

Using 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.

Moreover, the shield is easy to assemble with no soldering, and plugs right in to compatible HUB75 RGB LED Panels. he Teensy is removable, so you can swap between the 4.0 and 4.1 if you want. 


Features

Ease-of-use:

  • SmartLED Shield is fully assembled. If your Teensy has pins, then no soldering is required.
  • Teensy can easily be inserted into and removed from the shield.
  • SmartMatrix library for Arduino provides an easy development platform, along with others such as FastLED.
  • Example code is included for a quick start.

Flexibility:

  • Drives displays with up 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 to expansion rows for easy prototyping.
  • The 4-pin JST-SM connector may be used to provide power to the Teensy separate from the USB connector.
  • Optionally drive DotStar/APA102-compatible LEDs using the onboard 5 volt buffers and 4-pin JST-SM connector. Mating JST-SM cable is included.
  • Panels can be daisy-chained to make large, bright, high-resolution displays.
  • Drives all 14 signals on HUB75 panels using 5 volt buffered outputs, using only 9 GPIO pins on the Teensy 4.0 or 4.1.

Quality:

  • Provides up to a 240 Hz refresh rate.
  • Up to 48-bit color refresh is available.
  • Color (gamma) correction, and global brightness control features allow for a high level of visual quality control.


Main differences between the two units of Teensys

Teensys are small, well-featured, low-cost microcontroller boards. SmartLED Shield works with two variants of Teensy 4, the 4.0 and 4.1, with the 4.1 being the higher-powered option.

It is currently in the crowdfunding stage on the Crowd Supply. Go for supporting it if you are interested in it!
