: It is frequently found as a 20x4 character LCD or a graphic LCD display module .
The identifier KL SN102 94V-0 typically refers to an LCD display module
It often uses the Hitachi HD44780 protocol, though the pinout may differ from standard layouts. Interface: 16-pin connector including backlight pins. kl sn102 94v 0 datasheet pdf 18 exclusive
| Pin | Symbol | Function | Notes | | :-- | :--- | :--- | :--- | | 1 | VSS | Ground (GND) | Connect to 0V. | | 2 | VDD | Power Supply (+5V) | Main logic power. | | 3 | V0 / VEE | Contrast Adjustment | Connect to the wiper of a 10kΩ potentiometer between VDD and GND. | | 4 | RS | Register Select | 0: Command, 1: Data. | | 5 | RW | Read/Write | Connect to GND to disable reading. | | 6 | E | Enable Signal | Clock for data. | | 7-14 | D0-D7 | Data Bus | For 8-bit mode, use all. For 4-bit mode, use D4-D7. | | 15 | A | Backlight Anode (+) | Connect to +5V through a resistor (e.g., 220Ω) to limit current. | | 16 | K | Backlight Cathode (-) | Connect to GND. | | 17-18 | A/K | Backlight Duplicates | These often duplicate pins 15 & 16, possibly for mechanical stability. |
This is the most crucial part, indicating the flammability rating established by Underwriters Laboratories (UL). What is the 94V-0 Rating? : It is frequently found as a 20x4
Likely a manufacturer-specific project code, serial, or PCB design version.
Frequently found in older industrial environmental control units. | Pin | Symbol | Function | Notes
If you are hunting for a datasheet to fix a dimming or glitching screen in equipment like industrial monitors or audio gear, check these common failure vectors:
: Legacy systems suffer from oxidized contact pads. Disconnect the ribbon cables and clean them using high-purity isopropyl alcohol.
