LCD1602 IIC I2C Interface Adapter Plate

The standard 1602 LCD needs at least 7 wire connections to work. With this LCD1692 I2C Interface Adapter Plate, you only need a total of 4 lines for both data transmission and power. This LCD adapter is based on the PCA8574, and you can check the datasheet below for more information. Although the form-factor is perfect for 1602 displays, this adapter plate is also compatible with other displays, including LCD1601, LCD1604, and LCD2004. For experienced users, you can also use this as a General Purpose Input/Output expansion.
