Micro Dot pHAT


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.

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

As with our other pHATs, it works with all of the 40-pin Raspberry Pi variants - 3/2/B+/A+/Zero - but using it with the Pi Zero makes for a super-tiny package.


  • 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)

Kit includes:

  • Assembled Micro Dot pHAT PCB
  • 2x20 0.1" female GPIO header

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.

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.

Note: Our pHAT boards require you to solder on the headers and through-hole components!
