How to wire: GND—GND; VCC—VCC; SDA—A4; SCL—A5
Features: - Voltage: 5V DC
- LCD display type: Characters
- Module dimension: 80mm x 35mm x 11mm
Data： 1602 standard 16-pin interface, including:
Pin 1: VSS is the ground power.
Pin 2: VDD then 5V positive power supply.
Pin 3: V0 LCD contrast adjustment end, then the positive power supply when the contrast is the weakest, the highest contrast when grounded power, the contrast is too high will have a "ghosting", when used by a 10K potentiometer to adjust the contrast.
Pin 4: RS for the register selection, high-level data register selection, low-level instruction register selection.
Pin 5: R / W for the read and write signal lines, high-level read operation, low-level write operation.
Pin 6: E end is enable end, when E end jumps from high level to low level, the liquid crystal module carries out the order.
Pins 7 -14: D0 ~ D7 for the 8-bit bidirectional data lines.
Pin 15: the positive power supply backlight
Pin 16: backlight power negative
