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.

The CFA533-***-KC series is a 16x2 I2C LCD with keypad. The I2C interface allows you to use just two lines (SDA & SCL) to have bi-directional communication with the I2C LCD. Other devices can also share those two I2C control lines with the LCD. Only 4 wires are needed to connect this I2C LCD: power, ground, SDA (I2C Serial DAta) and SCL (I2C Serial CLock).

The CFA533 can run on 3.3v to 5.0v directly, with no changes needed, so you do not need to do any level translation between your embedded processor and the I2C LCD. Simply power the CFA533 from the same supply as your processor and the I2C signal levels will match up.

Using only one address on your I2C bus, you can add all the elements that you need for your front panel. The CFA533 I2C LCD can also read up to 32 DS18B20 digital temperature sensors, giving you an easy way to integrate temperature sensing over the I2C bus. No additional firmware or pins are needed on the host system.

This CFA533-TFH variant features crisp dark letters against a white, backlit background. The keypad has a matching white LED backlight. Since the LCD is a backlit positive FSTN, the CFA533-TFH I2C LCD is readable in direct sunlight, as well as complete darkness.

The 16x2 Alphanumeric LCD Display Module is equally popular among hobbyists and professionals for its affordable price and easy to use nature. As the name suggests the 16x2 Alphanumeric LCD can show 16 Columns and 2 Rows therefore a total of (16x2) 32 characters can be displayed. Each character can either be an alphabet or number or even a custom character. This particular LCD gas a green backlight, you can also get a Blue Backlight LCD to make your projects stand our and visually appealing, apart from the backlight color both the LCD have the same specifications hence they can share the same circuit and code. If your projects require more characters to be displayed you can check the 20x4 Graphical LCD which has 20 Columns and 4 Rows and hence can display up to 80 characters.

The 16x2 LCD pinout diagram is shown below. As you can see the module has (from right) two power pins Vss and Vcc to power the LCD. Typically Vss should be connected to ground and Vcc to 5V, but the LCD can also operate from voltage between 4.7V to 5.3V. Next, we have the control pins namely Contrast (VEE), Register Select (RS), Read/Write (R/W) and Enable (E). The Contrast pin is used to set the contrast (visibility) of the characters, normally it is connected to a 10k potentiometer so that the contrast can be adjusted. The Read/Write pin will be grounded in most cases because we will only be writing characters to the LCD and not read anything from it. The Register Select (RS) and Enable pin (E) pin are the control pins of the LCD and will be connected to the digital pins GPIO pins of the microcontroller. These pins are used to instruct the LCD where place a character when to clear it etc.

From DB0 to DB7 we have our eight Data Pins which are used to send information about the characters that have to be displayed on the LCD. The LCD can operate in two different modes, in the 4-bit Modeonly pins DB4 to DB7 will be used and the pins DB0 to DB3 will be left idle. In 8-bit Mode, all the eight-pin DB0 to DB7 will be used. Most commonly the 4-bit mode is preferred since it uses only 4 Data pins and thus reduces complexity and GPIO pin requirement on the microcontroller.Finally, we have the LED+ and LED- pins which are used to power the backlight LED inside our Display module. Normally the LED+ pin is connected to 5V power through a 100 ohm current limiting resistor and the LED- pin is connected to Ground.

16x2 LCD modules are very commonly used in most embedded projects, the reason being its cheap price, availability, programmer friendly and available educational resources.

16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but the most used one is the 16×2 LCD. So, it will have (16×2=32) 32 characters in total and each character will be made of 5×8 Pixel Dots. A Single character with all its Pixels is shown in the below picture.

Now, we know that each character has (5×8=40) 40 Pixels and for 32 Characters we will have (32×40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels. Hence it will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780is used, which is mounted on the backside of the LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen. You can learn how to interface an LCD using the above mentioned links. If you are an advanced programmer and would like to create your own library for interfacing your Microcontroller with this LCD module then you have to understand the HD44780 IC working and commands which can be found its datasheet.

RC1602C is a 16x2 character type LCD display with module dimension 85.0 x 36.0 mm. This monochrome display LCD 16x2 has built-in IC ST7066. Default interface of RC1601A module is 6800; if you require interface such as SPI or I2C, they’re available as well, but the IC will be replaced with RW1063.

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.

An easy way to add a simple visual interface to your project is by using an LCD Nanoshield. With it, you can display two lines of text with up to 16 characters. That allows you to show text messages or sensor data to the user, for example.

The internal LCD controller is compatible with the HD44780 chip from Hitachi, a de facto standard in the market for this kind of LCD. This is the same standard used in the LCD library that comes with the Arduino IDE.

The easiest way to use the LCd Nanoshield with an Arduino is to use the Base Board Uno or the Base Board L Uno. You just need to snap the boards together and upload our sample code to verify it"s working (see the code samples section below). This type of connection can be used with Arduino UNO, Mega R3, Duemilanove, and similar boards (contact us if you have questions about compatibility with other versions). The picture below shows how the final assembly looks like.

It is also possible to connect the LCd Nanoshield to our Arduino-compatible microcontroller board, the Base Boarduino. The connection is done in the same way as with the Base Board, as shown in the picture below. You just need to snap the boards together and upload our sample code to verify it"s working (see the code samples section below).

By using the Mini Terminal Nanoshield, it is possible to securely connect the LCD Nanoshield to an Arduino equipped with a Base Board or to a Base Boarduino. This connection uses only five wires, and is useful when the LCD needs to be mounted away from the Base Board – for instance when if must be mounted on a panel or case. The diagram below shows how to make that connection.

The LCD is equipped with a backlight that can be controlled via software by using the backlight() and noBacklight() methods in our Nanoshield_LCD software library.

Power supply: the board power is supplied via the VIN and VCC pins: VIN is optional but VCC is required. The recommended voltage range for the VIN pin is 7 to 12V (absolute maximum of 20V); the range for the VCC pin is 4.5 to 5.5V (5V typical). When there is power available in both pins, the VIN pin has priority and will be selected automatically to power up the LCD module and the backlight; in cases where there is no VIN available, the VCC pin will power up the whole board. The I2C expander comes pre-configured to work with 5V levels, using the voltage available on the VCC pins, but can also be configured to use 3.3V levels when this voltage is selected in the VI2C jumper on the board - donwload the schematics below for more details).
