: This is a graphic LCD display often identified by the "Kl sn102 94v-0 3320" marking. Character LCDs (20x4) : Some users have identified the module as a 20x4 character LCD . While many follow the standard Hitachi HD44780
Even though the component is 94V-0, the PCB itself must also be rated 94V-0. Maintain minimum clearance: Kl Sn102 94v-0 Datasheet
Prolonged exposure to moisture can cause pixel failure; cleaning connectors with isopropyl alcohol is recommended for restoration. Sourcing the Datasheet PDF : This is a graphic LCD display often
To use this module in custom projects (such as with an Arduino or STM32), developers must reference the pinout diagram usually found on page 2 or 3 of the official datasheet. Usually operates on a 3.3V or 5V logic level. The most significant line in any KL SN102
The most significant line in any KL SN102 datasheet is the rating. Without this, the component cannot be sold in many consumer markets (USA, EU, Japan).
