The **FYA-R220101ZX** is a high-brightness, surface-mount (SMD) **7-Segment LED Display** module manufactured by **Foryard Optoelectronics**. It is designed for displaying numerical data in electronic devices. --- ### 1. General Specifications This component is characterized by its physical dimensions and optical output. Below are the primary specifications: | Feature | Specification | | :--- | :--- | | **Digit Count** | Single Digit | | **Display Height** | 2.20 Inches (Large Format) | | **Technology** | LED (Light Emitting Diode) | | **Mounting Type** | Through-hole or SMD (Depending on specific series variant) | | **Polarity** | Common Anode or Common Cathode (Must verify via suffix) | --- ### 2. Optical Characteristics The "ZX" suffix usually denotes a specific color or brightness binning. Typical performance metrics for this series include: * **Luminous Intensity:** High output for visibility in bright environments. * **Peak Wavelength:** Varies by color (e.g., Red ~640nm, Green ~570nm). * **Viewing Angle:** Wide viewing angle (approx. 120°–160°). --- ### 3. Electrical Maximum Ratings To ensure the longevity of the part, the following electrical limits should be observed (at $T_a = 25^\circ C$): | Parameter | Typical Value | Unit | | :--- | :--- | :--- | | **Forward Current ($I_F$)** | 20 - 30 | mA per segment | | **Peak Forward Current** | 100 | mA | | **Reverse Voltage ($V_R$)** | 5 | V | | **Operating Temperature** | -40 to +85 | °C | --- ### 4. Circuit Diagram & Pinout Because this is a 2.20-inch display, each segment typically contains **multiple LED chips in series** to ensure uniform illumination across the large physical area. * **Voltage Drop:** Unlike small displays ($2V$), these large displays often require a higher forward voltage ($V_F$), typically between **6V and 9V per segment**, because of the series LED arrangement. * **Driving Requirement:** You will likely need a transistor-based driver or a dedicated LED driver IC (like the MAX7219) if your microcontroller operates at 3.3V or 5V. --- ### 5. Common Applications * Industrial clocks and timers. * Queue management systems. * Large-scale weighing scales. * Scoreboards and outdoor displays.
