Looking for a classic LED matrix display board? Here it is! The Pimoroni Micro Dot pHAT features six red LED matrices, each 5x7 pixels (30x7 effective display area) with a decimal point, using Lite-On LTP-305 matrices. It's perfect for building a retro scrolling message display, a 30-band spectrum analyzer, or a retro clock. Works with all 40-pin Raspberry Pi variants, especially great with the Pi Zero for a super-small setup. Key features include 3 onboard IS31FL3730 LED matrix driver chips, driving up to 6 red LTP-305 LED matrices, and a 30x7 pixel display. The kit comes with an assembled Micro Dot pHAT PCB, a 2x20 0.1' female GPIO header, and 6 red LTP-305 LED modules. It also works well with other pHATs and HATs, like combining with pHAT DAC for audio spectrum display or Enviro pHAT for temperature, pressure, and light readings. Note: Headers and LTP-305 modules need soldering. Suitable for any 40-pin Raspberry Pi.
Using the Pimoroni Micro Dot pHAT is easy. First, you'll need to solder on the headers and LTP-305 modules. Once that's done, connect it to your 40-pin Raspberry Pi. It works great with Pi 3, 2, B+, A+, or Zero, and is super tiny when used with the Pi Zero. You can use it to create a cool retro scrolling message display. Just program your Pi to show the messages you want. It can also be used as a 30-band spectrum analyzer or a retro clock. If you have other pHATs or HATs, you can combine them. For example, pair it with pHAT DAC to display the audio spectrum or with Enviro pHAT to show temperature, pressure, and light readings. When it comes to maintenance, keep it in a dry and clean place. If there's dust, use a soft brush to gently clean it. And always make sure to power off your Pi before making any connections or changes to the Micro Dot pHAT.
