Because "KL SN102" is often used for generic LCD boards or display modules, you may find it in various devices: LCD Modules
: Often associated with character or graphic LCDs (like 20x4 or 128x64 displays). Control Boards
: Found in industrial automation and power electronics, such as charging stations or ECU circuits. Replacement Parts
: Listed as "lab surplus" or "NOS" (New Old Stock) on sites like Where to Find Technical Documentation
Since there isn't one "official" global datasheet for a generic PCB number, use these resources to find the specific variant you have: Datasheet Archive : Search for "KL SN 102" on the Datasheet Archive
to find related wiring diagrams and application notes for industrial LCDs. Pinout Guides : If your board is an I2C LCD module, users on the Arduino Forum
suggest it may use standard HD44780 protocols or a PCF8574 interface. Inventory Listings : Specialized automation suppliers like Moore Automation
provide part-specific details for modules used in power plant DCS control systems. Technical Specifications (Common Indicators) Flammability : UL 94V-0 (Self-extinguishing material). Contrast Voltage : Boards marked with an 'S' in the corner may require a

If you are attempting to repair a device or identify a component:
The marking KL SN102 94V-0 refers to a specific type of LCD display module commonly found in legacy industrial equipment and automation systems. Component Identification
KL SN102: This is likely a manufacturer-specific part or batch number rather than a universal model number. It is often associated with products like the Stilo Grafica Colora HD Display or modules used in ABB automation systems.
94V-0: This is a UL flammability rating, not a technical specification of the display's performance. It indicates that the PCB material is self-extinguishing within 10 seconds and meets high safety standards for heat resistance. Technical Characteristics
While a single "universal" datasheet does not exist for this specific marking, technical discussions and listings reveal several common configurations:
Display Type: Typically found as either a 20x4 character LCD or a 122x32 graphic LCD.
Contrast Requirements: Some versions (noted by an 'S' in the corner) require a -5V negative voltage for contrast, rather than the standard 0–5V used by common Hitachi HD44780 modules.
Interface: Often uses a 20-pin interface. Users attempting to interface it with Arduino have noted that it may use the SED1520 controller or require specific I2C address configurations (e.g., 0x4e) if an expander is present. Availability and Sourcing
This component is frequently listed as "New Old Stock" (NOS) or surplus. You can find technical snapshots or buy replacements through: They share pinouts, 94V-0 rating, and similar dimensions
Industrial Surplus Sites: Platforms like MVME.cn list specific sub-models like the QH16465.
Secondary Markets: Listings on eBay often include the "GRAYM1005" control board variant.
Datasheet Repositories: Search The Datasheet Archive for contextual documents related to LCD bias solutions or similar PCB layouts.
