There is no single "datasheet" PDF for because it is not a specific electronic component model; rather, it is a marking found on printed circuit boards (PCBs) that indicates the board's substrate material and flammability rating . "94V-0" is a standard UL94 flammability certification meaning the material self-extinguishes within 10 seconds and does not drip flaming particles. This is the UL 94 flammability rating
: This is a critical safety standard, not part of the model number. It stands for UL 94V-0 (Underwriters Laboratories 94V-0) - a globally recognized flammability rating for the plastic materials used in the PCB. The "V-0" rating signifies the highest level of flame retardancy in its class, meaning any flame applied to the material will self-extinguish within 10 seconds. This is a mark of quality and safety, especially for industrial or automotive applications. It stands for UL 94V-0 (Underwriters Laboratories 94V-0)
Most modern LCDs use 0 to 5V for contrast, but some KL SN102 modules are requiring a negative 5V (-5V) supply for contrast adjustment to work correctly. Backlight: Typically uses standard 16-pin backlight pinouts. Control Chip: Some versions integrate a PCF8574 I2C interface IC for serial communication. Maintenance & Troubleshooting
This certification is critical for electronics safety. It signals that the base material (typically glass-fiber epoxy like FR-4) has strong self-extinguishing properties that effectively reduce fire risk, especially when a device experiences overcurrent, short circuits, or other faults that may generate heat.
The is a reliable, fire-resistant display solution for designers focusing on longevity and safety. By securing the correct datasheet and understanding its robust 94V-0 construction, you can seamlessly integrate this LCD into your next project.
