Jhd-2x16-i2c Proteus 💯 Newest

The is a 16-character by 2-line alphanumeric LCD module equipped with a PCF8574 I2C backpack . This backpack converts the standard 16-pin parallel interface of the HD44780 controller into a simple two-wire I2C interface (SDA, SCL), significantly reducing the number of GPIO pins required from a microcontroller.
