The SparkFun Qwiic Alphanumeric Display in brilliant green is a fourteen-segment digit display that elevates your projects with the capability to showcase not just numbers, but an array of characters and symbols as well. This user-friendly display integrates seamlessly with Qwiic, requiring no soldering or complex wiring, ensuring a smooth and hassle-free setup.
The SparkFun Alphanumeric Display Arduino library makes interfacing with the display a breeze. The library allows you to send I2C commands to the VK16K33 LED driver chip, which in turn lights up the segments. This includes the decimal point or colon, and even allows for scrolling text across the display. The library can be easily accessed through the Arduino library manager or downloaded as a .zip file from GitHub.
The VK16K33 also supports I2C address configuration, allowing up to four displays to communicate on the same bus. The slim design of the board includes detachable standoff holes, vertical Qwiic connectors, and internal mounting holes for easy installation.
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, reducing the amount of required PCB space and ensuring polarized connections for error-free hookup.
Features include a green display, operating voltage of 3.3V, an integrated RC oscillator, maximum display segment numbers of 128 patterns, a 13×3 matrix key scan circuit, a 16-step dimming circuit, I2C Addresses: 0x70 (0x71, 0x72, 0x73), 2x Qwiic connectors, and 2x Wall Mounting Points.
Documentation includes a schematic, Eagle Files, Board Dimensions, a Hookup Guide, a Datasheet (VK16K33), Qwiic Info Page, Arduino Library, and GitHub Hardware Repo. Get started with the Qwiic Alphanumeric Display Hookup Guide for easy setup and usage instructions.
