The 4-Digit 7-Segment Display from Sparkfun is a basic, white-colored display with a common anode. It features a decimal point for each digit, and the apostrophe and colon points can be individually controlled. This display is perfect for applications that require a clear and easy-to-read numeric output.
The LEDs in the display operate at a forward voltage of 1.9VDC and can handle a maximum forward current of 20mA. The interface is designed with sixteen through-hole pins, arranged in two rows of eight. This makes it easy to integrate into your electronic projects.
Although the datasheet for this display suggests it is blue, this is because the white version is essentially a blue display with a colored film over it. This means you get the brightness and clarity of a blue display, but with a softer, more neutral white light.
The 7-Segment Display is not limited to just white. Sparkfun also offers this display in yellow, green, red, and blue, allowing you to choose the color that best suits your project.
The display measures 40.18 x 12.8 mm, making it compact enough for most applications. The height of the digits is 10mm, ensuring they are clearly visible even from a distance.
To help you get started with using the 7-Segment Display, Sparkfun provides a datasheet and example code. These resources will guide you through the process of integrating the display into your projects and programming it to display the desired output.
