  I2C LCD Blue Board for Arduino                 

I2C LCD Blue Board for Arduino based on microchip MCP23008 provides 8bit I/O port expander with serial interface which can interface to several devices up to 8 devices on one bus. Each device must have a different address, three address pins, high-speed I2C interface 3400KHZ, and including LCD 16characters x 2lines with LCD-STN negative blue type is white character on blue background. LCD text & numeric display interface to I2C bus are SCL and SDA and support LCD contrast adjustment with fine adjustment of a trimpot to any desired contrast setting and support LED backlight-white to turn on or turn off the LED backlight with program control LED backlight to save power and including pull-up resistors to "pull-up" the signals to prevent SCL line & SDA line from floating. Pull-up resistors set default value when there is no signal at the input and including I2C bus cable to connect other boards on I2C bus and including JP6 Jumper to write data to LCD or read data from LCD. User can learn I2C LCD Blue Board with example programs as follows :
     - Autoscroll_I2C program
     - Blink_I2C program
     - Cursor_I2C program
     - Display_I2C program
    
- HelloWorld_I2C program
     - Scroll_I2C program
     - SerialDisplay_I2C program
     - setCursor_I2C program
     - TextDirection_I2C program

Board Feature :

  1. LCD 16characters x 2lines : LCD-STN negative blue type is white character on blue background. LCD text & numeric display interface to I2C bus are SCL and SDA.
  2. Including Microchip MCP23008 : 8bit I/O port expander with serial interface which can interface to several devices up to 8 devices on one bus. Each device must have a different address, three address pins, high-speed I2C interface 3400KHZ, voltage supply 1.8V to 5.5V, current 1mA.
  3. Support LCD Contrast Adjustment with fine adjustment of a trimpot to any desired contrast setting.
  4. Support LED Backlight-White to turn on or turn off LED backlight with program control LED backlight to save power.
  5. Including Pull-up Resistors to "pull-up" the signals to prevent SCL line & SDA line from floating. Pull-up resistors set default value (5Vdc) when there is no signal at the input.
  6. Including Libraries and Examples for learning quickly.
  7. Including a I2C Bus Connector to connect other boards on I2C bus are SCL line and SDA line. I2C bus connector consists of +5V, SCL, SDA and GND pin.
  8. Including I2C Bus Cable to connect other boards on I2C bus.
  9. Including JP6 Jumper to write data to LCD or read data from LCD.
  10. Operating voltage of I2C LCD Blue Board is 5Vdc.
  11. Board Dimension is 36.0mm(Width) * 80.0mm(Long) * 23.0mm(High).

Board Description :

  1. Trimpot Variable Resistor 10KΩ ± 10%, 0.5w to fine adjust LCD contrast to any desired contrast setting.
  2. JP4 Jumper & JP5 Jumper (Default) connect to pull up resistors for enable pull up resistors to "pull-up" the signals to prevent SCL line & SDA line and set default value (5Vdc) when there is no signal at the input.
    * If your another board have I2C bus system is pull up resistors that recommend you should be de-solder JP4 jumper and JP5 jumper to disable pull up resistors of I2C LCD Blue Board.
    * SCL is a serial clock line and SDA is a serial data line.
  3. Microchip MCP23008 provides 8bit I/O port expander with serial interface which can interface to several devices up to 8 devices on one bus. Each device must have a different address, three address pins, parallel I/O expansion for I2C bus or SPI applications, high-speed I2C interface 3400Khz, voltage supply 1.8V to 5.5V, current 1mA.
  4. A2, A1, A0 Jumpers will be set device address to interface your device. This I2C LCD Blue Board sets address = 0 (Default). A2, A1, A0 jumpers are disable.
    * If you must have interface to several devices up to 8 devices on one bus. Each device must have a different address and must solder A2, A1, A0 jumbers (Optional address = 0 to 7). A2, A1, A0 jumpers are enable.
  5. I2C Bus Connector to connect other boards on I2C bus are SCL line and SDA line. I2C bus connector consists of +5V, SCL, SDA and GND pin.
  6. JP6 Jumper will be set RW pin to write data to LCD or read data from LCD This I2C LCD Blue Board sets default to write data to LCD by solder JP6 jumper to connect GND. RW pin is cleared (0).
    * Optional is set RW pin to read data from LCD by de-solder JP6 jumper to disconnect GND. RW pin is (1).
  7. Pin Header 16pins connect between I2C and LCD.
  8. LCD 16characters x 2lines, LCD-STN negative blue type is white character on blue background, transmissive rear polarizer, 16x2 display format, 5x8 character format, 2.95x5.55mm. character size, LED backlight-white backlight, 62.2x17.9mm. viewing area, -20°C to +70°C operating temperature, 5Vdc voltage supply, 0.55x0.65mm. dot size, parallel Interface, white dot/blue background power on appearance. LCD text & numeric display interface to I2C bus are SCL and SDA.
