Pimoroni Four Letter pHAT for Raspberry Pi Zero

SKU AF-3475

AHOY, wanna spell out some LOVE with this COOL Raspberry Pi FOUR letter PHAT? Pimoroni's Four Letter pHAT has four 14-segment displays that you can use to display text, numbers, and a host of other characters. The LEDs are a beautiful retro green, just like your old digital alarm clock. They're driven by the HT16K33 chip over I2C, which does all the multiplexing for you. While it is shaped and sized to match a Pi Zero, it works great with any Pi with 2x20 connector.

It's perfect as a readout for your projects, displaying temperatures, times, etc. and becomes really useful when combined with some of Pimoroni's other boards like Enviro pHAT or Explorer pHAT to display their sensor values.


  • Four 14-segment displays with green LEDs
  • HT16K33 driver chip
  • Compatible with Raspberry Pi 3, 2, B+, A+, Zero, and Zero W (any 2x20 connector Pi)
  • Comes with an easy to use Python library

Kit includes: Four Letter pHAT PCB, two displays (four 14-segment displays total), and 2x20 0.1" female GPIO header. Some light soldering is required to attach the header and displays on, or you can of course solder the pHAT right onto the Pi.
