This IIC Serial I2C LCD Adapter Board, can be connected to a standard HD44780 compatible 16×2 or 20×4 Character Display Module that supports 4 bit mode. All Character Modules sold on our site support 4 bit mode, and nearly all commercially available 16×2 and 20×4 line character modules support it too.


This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on internet for using this board with Arduino. Do a search for “Arduino LCD PCF8574”. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one it’s own address).


Features IIC/I2C :

*   Arduino 1602 I2C interface 4-wire 1602 screen.

*   IO port of Arduino control board is only 20, so IO ports is not enough for many sensor, SD card, relay modules.

*   The original 1602 screen need 7 IO ports to drive up, and this module can save 5 IO ports

*   This is another great IIC/I2C/TWI/SPI Serial Interface. With this I2C interface module, you will be able to transfer data via only 2 wires. If you already have I2C devices in your project, this LCD module actually cost no more resources.

*   I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself)

*   Supply voltage: 5V

*   The backlight and contrast is adjusted by potentiometer

*   Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable

*   Compatible with 1602 LCD


Package includes :1x I2C Adapter for 1602 or 2004 Character LCD

Can be connected to 3.5-inch IDE parallel desktop hard drive, 2.5-inch IDE parallel laptop hard drive, 2.5/3.5-inch SATA serial laptop/desktop hard drive, DVD drive, DVD burning drive and other devices.



The Infrared Barrier Module is able to adapt to the environment light very well. Having a pair of infrared transmitter and receiver tube, the transmitter consistently emits a certain frequency. When an obstacle with reflective surface is encountered, the infrared reflected back is received by the receiver & sent to the comparator circuit for processing. The green light will lit and output digital signal (low). The detection range can be adjusted via the potentiometer knob.

650nm Laser sensor Module 6mm 5V 5mW Red Laser Dot Diode Copper Head KY-008


This 5V laser head is very easy to use, you can use Arduino control, make controllable laser pointer, theft detection, etc. interesting application devices.

As long as the laser can not point to itself or other eyes, even if the box is closed, the laser will have to open the possibility of error.

The laser is not a toy, does not give children, mental shortage, for people who do not know the use of laser characteristics, in this case, it can easily lead to injury.

The use of lasers must wear special glasses, for the invisible laser, this point is especially important.

The laser cannot shine on vehicles, airplanes and other transportation vehicles.

Condition: New Operating

Voltage :5V

Output wavelength 650 nm 3 pins module

With fixed bolt hole for easy installation

Color: show as pictures
