LCD1602 16×2 Blue LCD Display

LCD1602 16×2 Blue LCD is a character-type liquid crystal display that is a kind of dot matrix module that shows letters, numbers, characters, etc. It’s composed of 5×7 or 5×11 dot matrix positions; each position can display one character. There’s a dot pitch between two characters and a space between lines, thus separating characters and lines.

These displays are straightforward to use and are a great way to provide a user interface on many projects where you need more info than simple LED indicators or 7-Segment displays can provide since these are full alphanumeric displays with two lines of 16 characters each for a total of 32 characters.

For an interactive display, pairing this type of display with a rotary encoder to navigate and select menu items on display can provide an amicable user interface.

Specifications:

• Display Format: 16-character x 2-line Blue LCD
• Interface: HD44780
• Appearance: White on Blue
• Adjustable contrast
• Connection: Pin header
• Visual Area: 65 x 15mm
• 4-bit and 8-bit parallel interface
• 5V operation

Module Connections

The connection to the display is via a 16-pin header.

• VSS =        Connect to system ground.  This ground needs to be in common with the MCU.
• VDD =      Connect to 5V.  This can come from the MCU or be a separate power supply.
• VO =          Display contrast.  Connect to approximately a 20K potentiometer between 5V and ground to adjust the display’s contrast.
• RS =           Register Select.  Selects the command or data register.  A logic LOW = Command, HIGH = Data.
• RW =        Read / Write.  The display is a write-only device. This pin must be grounded to keep it in write mode.
• E =              Enable.  This pin enables writing to the display when active is LOW.
• D0 – D7 = Data pins.  D0-D7 is used for 8-bit mode.  D4-D7 used for 4-bit mode
• A =              Backlight Anode.  Connects to 5V.
• K =              Backlight Cathode.  Connects to ground.
