i2c 1602 lcd module display supplier

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 2 lines of 16 characters each.  For an interactive display, pairing this type of display with a rotary encoder to navigate and select menu items on the display can provide a very nice user interface.

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.

The backlight has a potentiometer for adjustment of the contrast of the display for best viewing.  If the potentiometer is turned too far in one direction or the other, the display will appear blank or solid squares will appear instead of characters.  If this happens, just fiddle with the adjustment until it gives the best display.

Note:  The non-uniformity in the picture is due to the protective film covering the display playing a trick on the camera.  The display has nice uniformity.

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.

A wide variety of i2c lcd options are available to you, such as original manufacturer, odm and agency.You can also choose from tft, standard and cob i2c lcd,

410 lcd 16x2 i2c products are offered for sale by suppliers on Alibaba.com, of which lcd modules accounts for 49%, character displays accounts for 24%.

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.

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.

The 1602 and 2004 LCDs are a popular choice for hobbyists, students and professionals alike. These LCDs are easy and quick to interface and allow for rapid prototyping and displaying of important information.

The 1602 and 2004 refer to the number of columns and number of rows the LCDs have. For example, the 1602 has 16 columns, and 2 rows. Similarly, the 2004 has 20 columns, and 4 rows. The characters are therefore displayed on a character matrix that is 16×2 and 20×4 for the 1602 and 2004 LCD respectively.

There are two common methods to connect the 1602 and 2004 LCDs to a microcontroller. The first is by using the available input and output pins along the top edge of the LCDs. Typically, it is not required to connect all 16 pins in order to get it working. A more convenient method is to use the “I2C backpack”, which converts the 16 pins on the LCDs to only 4 pins. Two pins are for power (5V and GND), and the other two are for the I2C bus (SDA and SCL).

In this option the I2C backpack is pre-soldered onto the back of the LCD. The most important feature about the I2C backpack is that it allows the LCD to be interfaced with a microcontroller very easily and quickly using only 4 wires. The following are features about the I2C backpack:

This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources for 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 module, you will be able to realize data display via only 2 wires.

This is great LCD display compatible with arduino. With limited pin resources, your project will quicly run out of resources using normal LCDs. With this I2C interface LCD module, you only need 2 lines (I2C)to display the information.If you already have I2C devices in your project, this LCD module actually cost no more resources at all. The adress can be set 0x27.
