i2c 1602 lcd module datasheet supplier

The display is composed of a 16 character x 2 line LCD display with a blue backlight and white characters.  Each of the characters are composed of a 5 x 8 dot matrix for good character representation.

This display incorporates an I2C interface that requires only 2 pins on a MCU to interface with and it has good library support to get up and running fast.   The I2C interface is a daughter board attached to the back of the LCD module.

If you need to adjust I2C address to avoid a conflict, this can be done on the I2C adapter board on the back of the module.  There are 3 address jumper locations marked A0, A1, A2.  Normally these lines are pulled high.  If you bridge these pads, it grounds that address line.  If you were to bridge all 3 to ground, the address would be 0x38 (or  0x20) depending on which version you have.  The range of all possible addresses spans from 0x38 – 0x3F or 0x20 – 0x27

These are good quality modules and should be in the parts bin of any hobbyist.  Because of the interactivity they provide, they are both fun to play with and useful for more serious projects.

We also offer the raw 16×2 displays without the I2C interface.  Those have a parallel bus interface that requires many pins on the MCU to control.  For most applications it is generally easiest to stick with the I2C interface version like this one.

Note that the I2C address of the module we sell is either 0x3F (63 decimal) or 0x27 (39 decimal) but can be adjusted if needed as explained above.  The address will be printed on the label on the bag.

This 2×16 character LCD Module with BLUE Backlight uses an I2C interface to communicate with the host microcontroller. This budget-conscious LCD is used on projects requiring the display of text, data, or ASCII characters of all types. Connect to Vcc, Gnd, SDA (serial data line), and SCL (serial clock line). This is a 5VDC device and will be found on the I2C bus at address 0x27 / 0x3F.

Winstar WO1602G is 16 characters x 2 lines COG Character LCD module with metal pin connection. This display is built in with ST7032I controller IC and it supports I2C interface. This series of module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.

This I2C LCD can display 16 characters on 2 lines and it features adjustable contrast and backlight. This I2C LCD is great for your project especially if you have limited pin resources, because it can be controlled by using only two pins.

An LCD display that can display a max of 16x2 charactors. with the help of the I2C bus convertor and related libraried, you can easily use this module with just 2 wires.

LCDs are great for printing data and showing values. Adding an LCD to your project will make it super portable and allow you to integrate up to 32 characters (16x2) of information.

This is another great blue/yellow backlight LCD display. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
