LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common,and easy to get,available in tons of colors and sizes. But it find that the number of pins necessary to control the LCD can be restrictive,especially with ambitious projects.The common character LCD need more than 6 pins for controlling. With the limited pin resources, your project may be out of resources using normal LCD shield. Here we provide the IIC LCD module, you only need 2 lines (I2C) to display the information.By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD.

• Support SPI
• Support IIC(Device Address:0x20 if other devices on the bus addresses with a repetition,you can change the address by shorting pad)
• 1602 character LCD
• Display color: Blue
