Qwiic Alphanumeric Display
£5.14 ex VAT
From digital alarm clocks to microwaves, seven-segment displays are used across a load of different electronic devices these days. SparkFun has upped the ante with these Qwiic Alphanumeric displays by including more segments! This means that you are able to display more than just numbers in your next project as these fourteen-segment digits allow you to display all sorts of numbers, characters, and symbols. With the added bonus of being Qwiic compatible, simply plug it in and go, no soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!
The SparkFun Alphanumeric Display Arduino library makes printing strings to the display as easy as calling the print() function. With this library, you'll be able to send I2C commands to the VK16K33 LED driver chip to light up segments (including the decimal point or colon) and even scroll your string across the display. You can download the library through the Arduino library manager by searching 'SparkFun Alphanumeric Display' or you can get the GitHub repo as a .zip file and install the library from there.
The VK16K33 also supports I2C address configuration. Simply close a combination of the address jumpers on the back and you can communicate with up to four displays on the same bus. The slim board design also features detachable standoff holes, vertical Qwiic connectors, and internal mounting holes.
