SparkFun Qwiic Alphanumeric Display - Red

The SparkFun Qwiic Alphanumeric Display - Red is a versatile device that takes the familiarity of seven-segment displays and enhances it with additional segments. This enhancement allows the display to present not just numbers, but also characters and symbols. The red fourteen-segment digits are powered with Qwiic, enabling a plug and play experience without the need for soldering or voltage regulation.

The SparkFun Alphanumeric Display is equipped with the VK16K33 LED driver chip, which can be easily controlled using I²C commands. This allows you to light up segments, including the decimal point or colon, and even scroll your string across the display. The Arduino Library for the SparkFun Alphanumeric Display simplifies this process, enabling you to print strings to the display with a simple print() function.

The VK16K33 also supports I²C address configuration, allowing you to communicate with up to four displays on the same bus. This is made possible by closing a combination of the address jumpers on the back. The slim board design of the SparkFun Qwiic Alphanumeric Display - Red also features detachable stand off holes, vertical Qwiic connectors, and internal mounting holes.

As part of the SparkFun Qwiic Connect System, this display is part of an ecosystem of I²C sensors, actuators, shields and cables designed to 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 polarized connections mean you can’t hook it up wrong.

Key features of the SparkFun Qwiic Alphanumeric Display - Red include a red 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.
