The LCD2S-162 is an RoHS-compliant Serial LCD Daughter board that can be connected to a standard 16x2-character display module that supports 4-bit mode. The default I2C address for these displays is 0x27. I2C (I-square-C i. By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD. This display has 4 lines of 20 characters each, giving you much more display capability than 16x2. VCC is the supply pin which is connected to Arduino 5V pin SDA is I2C bus serial data line, connected to Arduino analog pin 4 (A4) SCL is I2C bus serial clock line, connected to Arduino analog pin 5 (A5). However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. connecting all the wires from LCD to Arduino and some may have difficulty in finding I2C module and some with some other reasons. A library for I2C LCD displays. The pin 3 is not connected. Page 1 of 2 - 4X20 LCD display with I2C Interface - posted in Project Showcase: My holiday present to myself this year was the following 4X20 LCD: (link) It is based on the HD4478 LCD driver chip, front ended with an I2C interface, popular because it only uses two ports on your MCU. Check the humidity & temperature of your terrarium with a DTH22 humidity and temperature sensor and display this on an LCD I2C 16x2 display. About I2C LCD 1602 Display.
