Overview

Please see our tutorial (Tutorial: 1602 and 2004 LCDs) that outlines how to interface this LCD.

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 16x2 and 20x4 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).

NOTE: Please see our tutorial (Tutorial: 1602 and 2004 LCDs Rev0) on how to connect the 1602 and 2004 LCDs, with and without the I2C backpack.

I2C Backpack Option

In this option, the I2C backpack is pre-soldered onto the back of the LCD. The most important feature of 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 of the I2C backpack:

• I2C backpack is pre-soldered onto the back of the LCD.
• 4 male pins for the I2C bus (5V, GND, SDA, SCL).
• An onboard potentiometer adjust LCD contrast.
• 2-pin jumper for LED backlight (default is connected).
• Eight configurable addresses (default is 0x27).

No I2C Backpack Option

In this option there is no I2C backpack on the back of the LCD. Instead, the bare 16 input and output pin holes are exposed. The most important feature of this option is that it gives the user the most flexibility with their project. The user can directly connect the LCD to the microcontroller, or they can choose to solder their own I2C backpack as desired.

• No I2C backpack on the back of the LCD
• Most flexibility
• Pinout (from pin 1 to pin 16): VSS, VDD, V0, RS, RW, E, D0, D1, D2, D3, D4, D5, D6, D7, A, K
