This is a breadboard friendly, 2.54mm pitch, I2C controlled 8x2 characters LCD board for 5V microcontroller. It has the pull-up resistors for I2C bus in it. It is the 2.54mm pitch, so you can plug in the breadboard and Arduino. The pin assignment is same as Arduino Uno “Analog” pins which are used for I2C connection. It has the pull-up resistors for I2C bus in it, so all you have to do is to solder pin header you want to use. However, please be aware that you may want to remove the resistors if you connect other I2C devices on the same bus.
