Unit Puzzle is a colorful lighting control unit, composed of an 8x8 array with a total of 64 WS2812E RGB LEDs. Each LED is separated by a grid structure to prevent light interference from neighboring LEDs, ensuring clearer and purer visual effects. The product features two onboard Grove ports — one input signal port and one output port — and comes with a connector for linking multiple Unit Puzzle modules, expanding the light display area. The output Grove port also reserves an additional IO… (M5Stack U193)
