This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, 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 for Arduino based project.
Features:
- Support I2C protocol
- The power control with backlight can be set via jumpers backlight power supply is connected. Plug jumper to connect the backlight, then unplug the jumper is off backlight power supply
- The contrast can be adjusted by turning the blue potentiometer clockwise enhanced counterclockwise weakened.
- The module can cascade up to eight cascaded. / A1 / A2 modify the device address via short circuit A0.
- The default address is 0x27
Specifications:
- Dimensions: 42 x 19 x 15mm
- Weight: 5g
- Supply voltage: 5V (2,5...6Vdc)
Note: This is a "maker" module for developers. It is delivered without any further instructions than what you find here. |
