- 1602 I2C port 4-wire 1602 screen. IIC/I2C port The LCD1602 adapter does not contain an LCD screen. Control board IO port only 20, add some sensors, SD cards, relays and other modules, the IO port is not enough, The original 1602 screen requires 7 IO ports to drive, we developed this module can help you save 5 IO ports.
- Size :41.5mm(L)*19mm(W)*15.3mm(H). Weight: 5g. PCB color: black. Supply voltage :2.5-6V. Support the I2C protocol.
- With backlight power control, you can set whether to connect the backlight power through the jumper cap. Plug in the jumper cap to connect the backlight power supply, and remove the jumper cap to disconnect the backlight power supply.
- Contrast can be adjusted, rotate the blue potentiometer, enhance clockwise, diminish counterclockwise. Potentiometer design on the front, convenient for customers to freely adjust anytime and anywhere.
- Modules can be cascaded, and more than 8 can be cascaded. Short-circuit A0/A1/A2 to change the device address. The default address of the I2C board is 0x27.
