i2c 1602 lcd module display for sale

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.

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.

ERM1602SYG-6 is 16 characters wide,2 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with yellow green color included can be dimmed easily with a resistor or PWM,stn-lcd positive,dark blue text on the yellow green color,wide operating temperature range,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set. It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

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.

This 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight. It also includes a serial I2C/IIC adaptor board pre-soldered to the back of the LCD. This means it can be controlled with just 2 I2C serial data pins (SDA & SCL) and so requires far less digital IO pins when controlled from a microcontroller. In total the module only requires 4 wires including 5V power and GND. Contrast adjustment is also provided by the daughter board via a potentiometer. If you plan to use this with an Arduino board you can download a compatible library and example sketch from our support forum

These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have check the black I2C adaptor board on the underside of the module. If there a 3 sets of pads labelled A0, A1, & A2 then the default address will be 0x3F. If there are no pads the default address will be 0x27.

If pressure is applied to the I2C daughter board it is possible for it to bend and come contact with the LCD module. Please ensure when the LCD is installed in your application that no external object is applying pressure to the back of the module.

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.

Usually, Arduino LCD display projects will run out of pin resources easily, especially with Arduino Uno. It can also be very complicated with the wire soldering and connections. This I2C 16x2 Arduino LCD Screen is using an I2C communication interface, meaning it only needs 4 pins from your microcontroller for the LCD display to run: VCC, GND, SDA, SCL.

The display comes with a "Gadgeteer" cable which you"ll probably not need as the Gadgeteer wiring system is no longer produced! The display does not come with a dedicated cable for the I2C connection - we just use standard jumper wires instead.

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.

Here is pic shows how to connect an Arduino 1602 I2C module.The following is a table describing which pins on the Arduino should be connected to 1602 I2C LCD module.
