SparkFun Qwiic Alphanumeric Display - Purple

The SparkFun Qwiic Alphanumeric Display - Purple is a versatile, plug-and-play display module that adds a vibrant touch to your projects. With its purple fourteen-segment digits, it can display an array of numbers, characters, and symbols. The Qwiic connectivity feature eliminates the need for soldering or figuring out SDA or SCL, making it a hassle-free addition to your project.

The SparkFun Alphanumeric Display Arduino library simplifies the process of printing strings on the display. It allows you 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. The library can be downloaded through the Arduino library manager by searching 'SparkFun Alphanumeric Display'.

The VK16K33 also supports I²C address configuration, allowing communication with up to four displays on the same bus. The slim board design of this alphanumeric display includes detachable stand-off holes, vertical Qwiic connectors, and internal mounting holes.

The SparkFun Qwiic Connect System is a user-friendly 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, reducing the amount of required PCB space. The polarized connections ensure you can’t hook it up wrong.

The Qwiic Alphanumeric Display boasts several noteworthy features. It operates at a voltage of 3.3V and includes an integrated RC oscillator. It can display a maximum of 128 patterns, thanks to its 13x3 matrix key scan circuit. It also includes a 16-step dimming circuit, I²C addresses: 0x70 (0x71, 0x72, 0x73), two Qwiic connectors, and two wall mounting points.

For more detailed information, you can refer to the schematic, Eagle files, board dimensions, and the hookup guide. The datasheet for the VK16K33, the Qwiic info page, the Arduino library, and the GitHub Hardware Repo are also available.
