Based on available electronic component databases and standard naming conventions for display modules, the **FUDS-162-R.SLASHQ** (often referred to as FUDS-162) is a **16x2 Character LCD (Liquid Crystal Display)** module. These components are industry-standard for displaying simple text information in embedded systems. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Display Type** | Character LCD | | **Format** | 16 Characters x 2 Lines | | **Display Mode** | Usually STN (Super-Twisted Nematic) or FSTN | | **Backlight** | LED (Commonly Yellow-Green or Amber) | | **Controller IC** | Built-in HD44780 (or equivalent compatible) | | **Operating Voltage** | +5.0V (Standard) or +3.3V | | **Interface** | 4-bit or 8-bit Parallel | --- ### 2. Physical Characteristics * **Characters:** Each character is typically formed by a 5x8 pixel matrix. * **Slash-Q Designator:** The ".SLASHQ" suffix often refers to a specific manufacturing revision or a particular color/contrast configuration defined by the vendor (often related to reflective vs. transmissive properties). * **Pinout:** It typically utilizes a standard 16-pin header: * Pins 1-2: Power (VSS, VDD) * Pin 3: Contrast Adjustment (V0) * Pins 4-6: Control (RS, R/W, E) * Pins 7-14: Data Bus (DB0-DB7) * Pins 15-16: Backlight Power (LED+, LED-) --- ### 3. Electronic Driving Logic To interface this part with a microcontroller (like an Arduino, STM32, or PIC), the following logic is applied: 1. **Initialization:** The controller must send a specific sequence of commands to set the interface bit-width (4-bit or 8-bit) and clear the display. 2. **Contrast Control:** A potentiometer is usually connected to Pin 3 to adjust the visibility of the characters against the background. 3. **Command vs. Data:** The **RS (Register Select)** pin determines if the incoming byte is a command (like "move cursor") or data (the actual character to display). ```cpp // Example: Typical Pin Mapping for FUDS-162 style displays const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2; LiquidCrystal lcd(rs, en, d4, d5, d6, d7); void setup() { lcd.begin(16, 2); lcd.print("FUDS-162 Active"); } ``` --- ### 4. Common Applications * **Industrial Controls:** Displaying temperature or pressure readings. * **Consumer Electronics:** Microwave timers, coffee machine menus. * **Networking:** Simple status screens for routers or DIY servers.
