Gravity: Flexible 16x16 RGB LED Matrix SF_Transistors It requires at least 13Good news! There is a new member in to the Gravity family The Flexible 16x16 RGB LED Matrix! This module is a square panel with a soldered XH2. 54 3 pin interface with pin mappings that perfectly match the Arduino I O expansion shield . This flexible 16x16 RGB full color LED matrix module is based on WS2812 or SK6812 intelligent control LEDs. Each LED can be addressed independently with RGB pixels that can achieve 256 levels of brightness. That's
