Relay Switch and Electronic Module
I2C Module For 16X2 LCD for Arduino/Robotics
Product Highlights:
- Supply voltage: 5V
- The backlight and contrast is adjusted by potentiometer
- Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
- Compatible for 1602 LCD
- This is another great IIC/I2C/TWI/SPI Serial Interface
- With this I2C interface module, you will be able to realize data display via only 2 wires.
- If you already has I2C devices in your project, this LCD module actually cost no more resources at all.
- It is fantastic based project
