IIC/I2C Interface LCD1602 LCD screen adapter plate without
control board IO port is only 20, plus some sensor, SD card Han, relay modules and more, IO port is not enough,
The original 1602 screen requires 7 IO port can drive up, we have developed this module can help you save five IO ports, we send library
1 Dimensions: 41.5mm (length) * 19mm (W) * 15.3mm (height)
2 Weight: 5g
3.PCB Color: Black
4 Supply Voltage :2.5-6V
5 supports the I2C protocol
6 with backlight power control, can be connected via jumper settings are backlight power. Plug the jumper to connect the backlight off, unplug the jumper to disconnect the backlight power
7 Contrast can be adjusted by turning the blue potentiometer clockwise increase, counterclockwise weakened. Potentiometer design on the front, enabling customers to freely adjust anytime
8 modules can be cascaded to cascade up to eight. By short-circuiting A0/A1/A2 modify the device address. The default address is 0x27
