Hello! This time I want to present an 7-segment four digit display controlled by two 74HC595.The LEDs are connected in the common cathode configuration; this module is useful in electronic assemblies with Arduino or other development boards where you need to display numeric data, such as e.g. temperatures. For each digit, there are pins A, B, C, D, E, F, G, and DP. You don't have to solder the display, you can mount the display into female pins.

The representation of letter segments is universal. The 4-digit red LED display module, each with 7 segments, is useful in electronic assemblies where numbers must be displayed. Being 4 digits is useful for displaying time or to be a timer. The module has a common connection for each digit of the LED anode.

The circuit and also the bill of materials are available in the download section.

Pay attention to the pins configuration.
