For 3.3V systems like Raspberry Pi or ESP8266, use a level shifter or enable 3.3V-compatible mode if supported by the module variant. It pairs well with common sensors and I2C adapters to save pins.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eFor a standard Arduino setup, connect VSS to GND, VDD to 5V, V0 to the middle pin of a 10K potentiometer (with ends to 5V and GND), RS to digital pin 12, EN to pin 11, D4-D7 to pins 5-4-3-2. Tie R\/W to GND. In code, use the LiquidCrystal library with 4-bit mode.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
