Micro Dot pHAT

by Pimoroni

An unashamedly old school LED matrix display board, made up of six LED matrices each 5x7 pixels (for an effective display area of 30x7) plus a decimal point, using the beautiful little Lite-On LTP-305 matrices.

Use between 1 and 6 matrices in your choice of green and/or red. Perfect for building a retro scrolling message display, a tiny 30-band spectrum analyser, or a retro clock.

Micro Dot pHAT also works well with our other pHATs and HATs. You could use it in combination with pHAT DAC to display the audio spectrum, or with Enviro pHAT to display its temperature, pressure and light readings.

The MagPi said that Micro Dot pHAT was "certainly a cut above the standard seven-segment alternative" in their four star review.

Available either as a bare pHAT or as a kit with 6 red or green LED modules (you'll need to solder them yourself)

Features

  • 3x IS31FL3730 LED matrix driver chips
  • Drives up to 6x LTP-305 green and/or red LED matrices
  • Up to 30x7 pixels (5x7 per matrix plus a decimal point)
  • Micro Dot pHAT pinout
  • Compatible with all 40-pin header Raspberry Pi models
  • Python library
  • Female header and display require soldering
  • Schematic

Software

We've put together a comprehensive Python library to make using Micro Dot pHAT really simple, as well as a guide to assembling it, and a getting started guide to show you how to install and use the Python library.

I like the micro dot pHAT as it works really well with these light matrix Pimoroni sells. I tried out the example code and was able to get things working in quick order without much issue. Soldering wasn't too bad albeit there were a lot of pins to solder in this full set so be aware you have some work ahead of you. I'd consider using these for future projects where I need to show off a counter of some form as it really gives a neat effect. Would recommend.

This needs some connection notes with it otherwise it will not be used

Beautiful displays - I first used these individual chips over 50 years ago; these are much easier to use with the integral driver - thank you Pimoroni.

I love the retro feel of this display. I have it attached to a Raspberry Pi WH and I'm using it as a clock just above my computer monitor. It's brilliant. The display is easily clear enough to read without blinding you. I used the clock example from the Getting Started Guide and just set it to run automatically when the Pi boots. There's a bit of soldering involved but it's quite straight forward.

A Beautiful thing and great fun for experimenting with python! The soldering took some time and I had to resolder some joints. It is very easy to use with the fantastic python library!

Beautiful display. Ive made a clock with one, and plan on adding another to a small raspberry pi computer (cyberdeck) I’m putting together.

Looks cool, easy to use (thanks to the Python library) and not too difficult to solder.
