Jhd-2x16-i2c Proteus May 2026

JHD-2X16-I2C is a popular alphanumeric liquid crystal display used in Proteus simulations and real-world electronics projects. It integrates a standard 16x2 LCD with an I2C communication interface (typically using the

Important: In Proteus, if using PCF8574 + LM044L, connect PCF8574’s P0–P7 to LM044L’s RS, RW, E, D4–D7 as per standard 4-bit mode. But the prebuilt LCD I2C model simplifies this. jhd-2x16-i2c proteus

The JHD-2x16-I2C is a 16-character by 2-line LCD module commonly simulated in Proteus to visualize character data while saving microcontroller I/O pins. In a physical setup, this typically combines a standard JHD162A (or similar) LCD with a PCF8574 I2C backpack. 1.
