Description
About this item:
The JHD 162A 16×2 LCD Display Module is a widely used alphanumeric display for embedded systems and DIY electronics. It provides a clear two-line, 16-character-per-line text display, making it suitable for projects that require simple and effective user interaction.
This module uses the industry-standard HD44780 controller, ensuring broad compatibility with Arduino, Raspberry Pi, microcontrollers, and development boards. It can be interfaced in either 4-bit or 8-bit parallel mode, requiring multiple I/O pins, or with an I2C adapter, which reduces the pin requirement to just two (SDA, SCL).
The display typically comes with a yellow-green LED backlight, though variants with blue or other colors are also available. It operates on 5V DC, making it easy to integrate into most digital circuits.
