The SparkFun Alphanumeric Display is supported by a dedicated Arduino library, which simplifies the process of printing strings to the display. With this library, you can send I2C commands to the VK16K33 LED driver chip, enabling you to light up segments, include decimal points or colons, and even scroll text across the display. The library is easily accessible through the Arduino library manager or the GitHub repository.
The VK16K33 also supports I2C address configuration, allowing for communication with up to four displays on the same bus. The slim design of the board includes detachable stand-off holes, vertical Qwiic connectors, and internal mounting holes for convenience and flexibility in mounting.
The SparkFun Qwiic Connect System is an ecosystem that streamlines the prototyping process, reducing errors and speeding up development. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, which saves on PCB space and ensures correct, polarized connections.
The SparkFun Qwiic Alphanumeric Display - White offers numerous features, including a white display, an operating voltage of 3.3V, an integrated RC oscillator, and a maximum display of 128 segment numbers. It also includes a 13x3 matrix key scan circuit, a 16-step dimming circuit, I2C addresses, 2x Qwiic connectors, and 2x wall mounting points.
Additional resources such as schematics, Eagle files, board dimensions, hookup guide, datasheet, Qwiic info page, Arduino Library, and GitHub Hardware Repo are provided for further support and information.
