The Micro Dot pHAT is a super cool, old - school LED matrix display board. It's made up of six 5x7 - pixel LED matrices (resulting in a 30x7 effective display area) and a decimal point, using the lovely Lite - On LTP - 305 matrices. You can choose to use 1 to 6 matrices in either green or red. It's perfect for creating a retro scrolling message display, a tiny 30 - band spectrum analyser, or a retro clock. This pHAT also works great with our other pHATs and HATs. For example, pair it with pHAT DAC to show the audio spectrum or with Enviro pHAT to display temperature, pressure, and light readings. As The MagPi said in their four - star review, it's 'certainly a cut above the standard seven - segment alternative'. You can get it as a bare pHAT or as a kit with 6 red or green LED modules (soldering required). Features include 3x IS31FL3730 LED matrix driver chips, compatibility with multiple Raspberry Pi models, a Python library, and more. Note that female header and display need soldering, and our software doesn't support Raspbian Wheezy.
Using the Micro Dot pHAT is a breeze. First, if you get it as a kit, you'll need to solder the 6 red or green LED modules and the female header. Once it's assembled, connect it to your Raspberry Pi (it's compatible with Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W). We've provided a Python library to make things easy. Just follow our getting - started guide to install and use this library. When using it, you can choose to use 1 to 6 matrices in your preferred color (green or red). You can use it for different projects like making a scrolling message display or a spectrum analyser. Remember, our software doesn't support Raspbian Wheezy, so make sure your Raspberry Pi has a compatible operating system. As for maintenance, keep it in a dry and clean place. If there are any issues with the soldered parts, you may need to re - solder them carefully.
