Using your LTP - 305 LED matrices is a breeze. If you choose to use our Micro Dot pHAT board, just connect the matrices to it. You can use up to 6 matrices together, and you can pick the colors you like. You can also connect the matrices directly to a microcontroller or a matrix driver chip like the one on our Micro Dot pHAT. When using, make sure the power supply is stable to avoid any display issues. Don't expose the matrices to extreme temperatures or moisture. For maintenance, simply keep them clean with a soft, dry cloth. If you have any problems, check the connections first. That's all you need to know to enjoy these great LED matrices!
