Using the Micro Dot pHAT is easy. First, if you've bought the kit, you'll need to solder the 6 red or green LED modules onto the board. Make sure to do this carefully as the female header and display also require soldering. Once it's assembled, connect it to your Raspberry Pi. The supported models are Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W. We've provided a Python library to make things simple. Just follow the getting - started guide to install and use it. When using the pHAT, you can customize the number of matrices (from 1 to 6) and choose between green and red colors. You can use it for different projects like creating a scrolling message display or a spectrum analyser. Remember, our software won't work with Raspbian Wheezy. For maintenance, keep the board clean and free from dust. Avoid exposing it to extreme temperatures or moisture. If you face any issues, refer to the assembly guide and the documentation of the Python library.
