§ 02 — Description

Classic LCD 1602 character display supplied with an I2C adapter based on the PCF8574 chip, making it easy to output text and numeric information in projects with Arduino, ESP32 and Raspberry Pi. Port saving (I2C): The adapter converts the 8/4-bit parallel HD44780 interface into a 2-wire I2C bus, freeing the microcontroller's digital pins for connecting other sensors and actuators. Easy setup: The I2C module board has a trimmer resistor for precise contrast adjustment of the characters, as well as a jumper for software or hardware switching off of the backlight. High readability: The high-contrast blue screen with white characters ensures excellent readability of information under any lighting.
