The **FYA-R1408ZX** is a high-performance electronic component, specifically a **1.4-inch Single Digit 7-Segment LED Display**. This part is commonly used in digital clocks, instrument panels, and electronic meters to display numeric information. --- ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the FYA-R1408ZX: | Feature | Specification | | :--- | :--- | | **Digit Height** | 1.4 Inches (35.56 mm) | | **Configuration** | Single Digit | | **Emitting Color** | Typically Red (High Efficiency) | | **Polarity** | Common Anode (ZX usually denotes configuration) | | **Forward Voltage ($V_F$)** | 1.8V to 2.2V per segment | | **Operating Current ($I_F$)** | 20mA (Recommended) | | **Luminous Intensity** | 30 - 60 mcd | | **Surface Color** | Black face with white segments | --- ### 2. Segment Architecture Like standard 7-segment displays, this part consists of 7 individual LEDs arranged in a figure-eight pattern, with an 8th LED for the decimal point (DP). * **Segments A-G:** Form the numerical digits 0-9. * **DP:** Decimal point for fractional values. * **Internal Circuitry:** In a **Common Anode** version, all the positive terminals (anodes) of the LEDs are tied together to a single pin, while the individual segments are turned on by grounding their respective cathodes. --- ### 3. Connection Example To interface this display with a microcontroller (like an Arduino or ESP32), you must use current-limiting resistors to prevent burnout. ```cpp // Example: Mapping segments to Arduino Pins int segA = 2; int segB = 3; int segC = 4; // ... and so on void setup() { pinMode(segA, OUTPUT); // Common Anode: Write LOW to turn ON the segment digitalWrite(segA, LOW); } ``` --- ### 4. Key Applications * **Industrial Controllers:** Displaying temperature or pressure readings. * **Consumer Electronics:** Microwave timers or digital scales. * **Scoreboards:** Large digit size makes it suitable for visibility from a distance. * **Testing Equipment:** Multimeters and frequency counters.
