The **EBWL2107FZGS-D** belongs to a specific category of Electronic Shelf Label (ESL) modules or specialized display assemblies typically used in industrial and retail automation. Below is a detailed breakdown of its electronic composition and technical characteristics. ### Technical Overview This part is essentially a **2.13-inch 3-Color E-Paper Display Module**. It is designed for ultra-low power consumption and high visibility under various lighting conditions. --- ### Core Electronic Components | Component | Description | Function | | :--- | :--- | :--- | | **E-Ink Panel** | 2.13" Electrophoretic Display (EPD) | Provides the visual output (Black/White/Red). | | **Display Controller** | Integrated Source/Gate Driver IC | Manages the voltage levels to move microcapsules. | | **Interface** | SPI (Serial Peripheral Interface) | 3-wire or 4-wire communication with a MCU. | | **FPC Connector** | Flexible Printed Circuit (24-pin usually) | Connects the glass panel to the main PCB. | | **Internal EEPROM** | Non-volatile Memory | Stores specific waveform look-up tables (LUT). | --- ### Key Specifications 1. **Display Resolution:** Typically **212 x 104 pixels**, providing sharp text and barcode rendering. 2. **Color Depth:** 3-Color (Black, White, and Red). 3. **Power Consumption:** * **Refresh Power:** ~10-15 mW (only consumes power during an image update). * **Standby Power:** Near zero (<1uA) as the image remains static without power. 4. **Viewing Angle:** >170°, making it readable from almost any direction. 5. **Operating Voltage:** 2.3V to 3.6V (Standard CMOS levels). --- ### Typical Pinout Configuration (24-pin FPC) If you are integrating this into a circuit, the primary pins follow this logic: ```cpp // Common SPI Pin Mapping for EBWL series 1. VCC -> 3.3V Power Supply 2. GND -> Ground 3. SDI -> MOSI (Master Out Slave In) 4. SCLK -> Serial Clock 5. CS -> Chip Select (Active Low) 6. D/C -> Data/Command Control 7. RST -> External Reset 8. BUSY -> Busy Status Output (Wait for high/low before next command) ``` --- ### Application Usage These modules are commonly found in: * **Retail:** Smart price tags that update via Zigbee or Bluetooth gateways. * **Logistics:** Reusable shipping labels and warehouse bin markers. * **IoT Devices:** Low-power weather stations or cryptocurrency tickers. ---
