When troubleshooting a device and encountering "KL SN102 94V-0" printed on a green or black PCB, it is easy to mistake the entire string for a unique part number. In reality, this text contains three distinct pieces of manufacturing data. 1. KL (Manufacturer or Series Identifier)
The "KL SN102" or "KL SN102-94v-0" primarily points towards a . This is supported by multiple community findings, where users confirmed these modules had 16 or 20 pins and were used as drop-in upgrades from the standard 16x2 displays. Some later models also had the marking "LCM015 R2.1" in conjunction with "KL SN102 94V-0".
Search for the datasheet of that specific chip . The chip's datasheet will usually feature a which often matches 90% of the traces on your specific "KL-SN102" board. 3. Use Trusted Engineering Repositories kl sn102 94v 0 datasheet pdf 18 exclusive
These boards are typically populated with monochrome LCD displays, often 20x4 or 16x2 character displays, used in devices like industrial controllers, calculators, and POS systems. They are commonly found on Alibaba and Enlcd as industrial LCD panel replacements. Technical Specifications and Features
Likely a manufacturer-specific project code, serial, or PCB design version. When troubleshooting a device and encountering "KL SN102
Because this is a generic PCB manufacturing code, replacing the unit means looking for the manufacturer's module number rather than the board marking itself.
: Maintains dimensional integrity during reflow soldering and can operate in temperatures ranging from roughly -40°C to +130°C Technical Applications Application Benefit of KL SN102 Industrial PLCs & Motor Drives Stable operation in harsh environments Diagnostic Tools High regulatory compliance and precision Automotive ECUs & Infotainment Vibration resistance and wide temp range Control Boards (e.g., Fostex VF-160) High flame retardancy for enclosed systems Purchasing & Sourcing KL (Manufacturer or Series Identifier) The "KL SN102"
