The Micro Dot pHAT is a retro-style LED matrix display board for Raspberry Pi, designed to drive up to six Lite-On LTP-305 LED matrices. Each 5×7 pixel matrix includes a decimal point, giving you an effective display area of 30×7 pixels across all six modules.

Use between 1 and 6 matrices in your choice of green and/or red for scrolling message displays, spectrum analysers, clocks, or sensor readouts. This listing is for the bare pHAT board only — LED matrix modules are sold separately.
