The Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWing makes it easy to add a numeric display to any Feather project. The HT16K33 driver handles all LED multiplexing over I2C, so your Feather only needs two shared pins — leaving all other GPIO free for sensors, buttons, and additional displays.

This is the FeatherWing board only — no 7-segment display is included. It supports 4-digit 0.56" 7-segment displays with decimal points and a centre colon for clock applications. For a ready-to-go combo, choose one of the colour packs listed below.
