LCD1602 Keypad Shield 16x2 HD44780 Character Module Display Yellow Screen[Description]The LCD1602 is an industrial character LCD that can display 16x2 or 32 characters at the same time.The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage, that is, the graphic can be displayed.The 1602 uses a standard 16-pin interface, and our display module is a module that provides I2C functionality.I2C uses only two offerirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL),pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted. It can be operated as long as it supports the I2C development board.For example, the common Ar-duino, raspberry pi, Stm32 and so on.Features: Easy to use; Less I/O ports are occupied; Support IIC Protocol; The I2C LCD1602 library is easy to get; With a potentiometer used to adjust backlight and contrast; Yellow backlight; Power supply: 5v; I2C address is: 0x27.Blue Backlight is here align="start" style="box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px; margin: 0.3em 0px 0px 1.6em; padding: 0px; list-style: disc; margin-block: 1em; margin-inline: 0px; padding-inline-start: 40px; color: rgb(34, 34, 34); font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; font-family: sans-serif; background-color: rgb(255, 255, 255);">
