4 digit 7 segment LED Display Common Anode CA

High-Quality PCB for Assembling a 4-Digit Common Anode 7-Segment LED Display Module

Our high-quality PCB offers exceptional features and scalability for assembling a 4-digit common anode 7-segment LED display module. This module is perfect for various applications, including clocks and status indicators.

Optional Middle 2-Point LEDs for Clock Seconds Blinking:

The module includes middle 2-point LEDs that can be optionally connected to the DP segment of DISP 3. This feature allows for seconds blinking specifically for clock purposes.

3 Additional Selectable LEDs for Status Indication:

For status indication purposes, we offer 3 additional selectable LEDs. These LEDs can be optionally chosen and connected to the DP segment line of DISP 4, 2, and 1 respectively.

Multiple Interfacing Options to Meet Circuit Demands:

Our PCB board provides multiple interfacing options to meet various circuit demands. These options include:

    ULN2803 Driver-Based Parallel Interfacing
    Shift Register with Latched Output (IC 74HC595) Interfacing: This version includes a cascading output connector for enhanced functionality.
    Shift Register without Latch (IC 74HC164) Interfacing.

Shift Register Options with ULN Driver IC:

For the shift register versions, you have the option to include or exclude the ULN driver IC. If the ULN driver IC is included, the data should be in non-complemented form. If the ULN driver IC is not included, the shifted data should be in complemented form.

Multiplexed Micro Tactile Switches:

The module features 4 micro tactile switches that are multiplexed to a single point. This allows for easy reading of switch values using an ADC pin.
