The is a 16x2 character Liquid Crystal Display (LCD) equipped with an integrated I2C (Inter-Integrated Circuit) adapter, typically based on the PCF8574 expander chip . This module is a staple in embedded systems prototyping because it reduces the required microcontroller I/O pins from at least six (in parallel mode) down to just two: SDA (Serial Data) and SCL (Serial Clock). jhd-2x16-i2c proteus
