Pin7 (Data Pin): The data pins are from 0-7 which are connected through the microcontroller for data transmission.This pin is connected to the data pin of the microcontroller to be held high constantly. Pin6 (Enable): This enables the pin must be high to perform the Read/Write procedure.Pin5 (Read & Write): This pin is used to read/write data.Pin4 (Register Select): This pin is used to connect a data pin of an MCU & gets either 1 or 0.Pin3 (VE): This pin selects the contrast of the LCD.Pin2 (+5 Volt): This pin provides a +5V supply to the LCD.Pin1 (Ground): This pin connects the ground terminal.The pin configuration of LCD 16 X 2 is discussed below so that LCD 16×2 connection can be done easily with external devices. Font size of character is 0.125Width x 0.200height.Pixel box of each character is 5×8 pixel.LED color for backlight is green or blue.PCB size of the module is 80L x 36W x 10H mm.The operating current is 1mA without a backlight.The operating voltage of this display ranges from 4.7V to 5.3V.The specifications of LCD 16X2 are discussed below. There are different types of displays available in the market with different combinations such as 8×2, 8×1, 16×1, and 10×2, however, the LCD 16×2 is broadly used in devices, DIY circuits, electronic projects due to less cost, programmable friendly & simple to access. 16 X2 displays mostly depend on multi-segment LEDs. ![]()
