Dorhea 2PCS IIC I2C TWI - Review

If you’re into building projects with Arduino boards, Raspberry Pi or other micro-controllers, then you should definitely check out the Dorhea 2PCS IIC I2C TWI Serial LCD 2004 20x4 Blue Backlight Module with I2C Interface Adapter. This kit is perfect for displaying information and messages in your project, and it is both easy to use and set up. In this review, we will go over the details of the product and share our thoughts on how it performs.

Firstly, let’s talk about what you get in the package. When you purchase the Dorhea 2PCS IIC I2C TWI Serial LCD 2004 20x4 Blue Backlight Module with I2C Interface Adapter, you will receive two LCD 2004 display modules with blue backlight, and three IIC/I2C/TWI serial interface adapters. The module displays 20 characters in one row, and 4 rows can display 80 characters, making it perfect for displaying messages or information in your project.

The IIC/I2C/TWI serial interface adapter is an interface board that allows you to use only two I/O ports while communicating with the LCD module using I2C protocol, which is a serial communication protocol that requires only two wires to transmit the data. This means that the module uses less I/O ports, and you will have more ports left for other usages.

The module’s address is either 0x27 or 0x3F, and you can set it by using the solder bridges on the IIC/I2C/TWI serial interface adapter. You can also adjust the contrast of the LCD display by using the potentiometer at the back of the module, which is very convenient. Additionally, if you don’t want the backlight, you can unplug the jumper cap at the back of the module.
