Unit-Puzzle is a multi-color light control unit consisting of an 8x8 RGB array made up of 64 WS2812E RGB LEDs. Each LED is separated by an isolation structure to prevent interference between adjacent lights, ensuring the light effect is clearer and purer. The product features two onboard Grove connectors-one for input signal and the other for output, with a connecting piece included for linking multiple Puzzle units to extend the lighting display area. The Grove interface also includes an IO port for connecting other M5 devices, such as a potentiometer, to enable more interactive control functions. Unit-Puzzle is compact, easy to install, and features an M2 mounting hole on the bottom for secure fixing. This product is suitable for applications such as smart lighting, decorative displays, and interactive installations. LED Brightness: Continuous high brightness may cause damage; it is recommended to use 10% brightness to reduce heat and power consumption.
