SparkFun Qwiic Alphanumeric Display Kit

We are quite familiar with seven-segment displays. We see them on our alarm clocks, ovens, and microwaves. By adding more segments to each digit you can display more than just numbers! These fourteen-segment digits allow you to display all sorts of numbers, characters, and symbols. With Qwiic, 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 Qwiic Alphanumeric Display Kit comes with six displays, one red, white, green, blue, pink and purple. Also included in this kit are enough Qwiic cables to get up and running as fast as possible. With a wide variety of Qwiic enabled microcontroller boards available we decided not to include one so you could choose the one that fits best with your current project needs. This is the only part you need to supply yourself, so be sure to check the Hookup Accessories below for some suggestions!

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. Our slim board design also features detachable standoff holes, vertical Qwiic connectors, and internal mounting holes.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you canââ�¬â�¢t hook it up wrong.
