Introduction

Seven segment displays are SO 2020. I mean, we see them in our clocks, ovens, and microwaves on the daily. But what happens when you add more segments to each digit? You can upgrade your appliances and let everyone know how you REALLY feel. Introducing SparkFun's newest Qwiic-Enabled Alphanumeric Display in Pink, Green, Blue, Red, Purple, and White. Customize that microwave alert - "Your food is done, fool!" Or hack those oven messages - "I pity the fool that doesn't pre-heat!" These fourteen-segment digits allow you display all sorts of numbers, characters, and symbols. Let's jump in and have a look, shall we?
