i2c Driver Backpack Board for LCD (16x02, 20x04)
This i2c Driver Backpack Board for LCD reduces the number of pins required to control an LCD Display from 16 pins to 2 pins (i2c SDA and SCL). Now you can save and use the other extra pins to connect other sensors or for any input/output. This i2c driver backpack works with any standard character LCD from 8x1 to 20x4 sizes as long as they have a 16-pin single-line connection header at the top just like the 16x02 and 20x04 LCD displays that we stock. This i2c driver is based on the widely known PCF8574A i2c driver chip.
Note: try 0x27 or 0x3F for your i2c address code.
