Four Letter pHAT

Use Four Letter pHAT to display... four letter words. Not that sort!

Four Letter pHAT has four 14-segment displays that you can use to display text, numbers, and a host of other characters. Its LEDs are a beautiful retro green, just like you old digital alarm clock. They're driven by the HT16K33 chip over I2C.

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