Description
This is another great serial IIC/I2C/TWI/SPI interface. Because the controller's pin resources are limited, your project may not be able to use normal LCD shielding after a certain number of sensors or SD cards are connected. However, with this I2C interface module, you can display the data via only 2 wires. If you already have I2C devices in your project, this LCD module does not cost any resources at all. It's fantastic for a based project.
I2C address: 0x20 ~ 0X27 (the original address is 0x20, you can change it yourself) the backlight and the contrast are set with a potentiometer.
2 IIC interfaces are included, which can be connected via Dupont Line or an IIC cable. I2C address: 0x27 (I2C address: 0x20 ~ 0X27 (original address is 0X27, you can change it yourself)
