Displays 4-lines X 20-characters.Backlight (White character on Blue background).
With Backlight, the backlight can be turned on or off via a jumper cap. Contrast can be adjusted with a blue potentiometer, clockwise and counterclockwise. Power supply: DC 5V; You can connect directly to arduino board.
Module dimension: 98mm x 20mm x 20mm.
Viewing area size: 76mm x 26mm.
Point size: 0.55mmx0.55mm;
Character size: 29.5mmx47.5mm;
Weight: 55g.
Arduino IIC/I2C interface was developed to reduce the IO port usage on Arduino board.
I2C Address: 0x3F or 0x27 (can be by by scanning);
The device address can be modified by connecting: A0/A1/A2.
Address modification instructions (take the default address 0x27 as an example)
A0, A1, A2 all disconnected address is 0c27;
A0 connection: the address is modified to: 0x26;
A1 connection: the address is modified to: 0x25;
A3 connection: the address is modified to: 0x23;
......
A0, A1, A2 all links, the address is modified to: 0x20;
How to connect:
GND: POWER -;
VCC: POWER -;
SDA: IIC data line;
SCL: IIC clock line;
Old 2004 screen requires 7 IO ports but this module uses only two. Much needed control panel IO ports can be used to add some sensors, SD card and so on. Package List:
1x IIC/I2C/TWI 2004 Serial LCD Module.
