【20x4 LCD Display】With this shield, you can display whatever you want by programming the for Arduino board. Therefore, this is a perfect choice to make your project more interesting and vivid! Totally display 20 characters in one row, 4 rows can display 80 characters..
【IIC Interface Adapter】No need to buy the adapter extra, this kit contains a IIC/I2C/TWI Serial Interface Adapter, with witch you can start your project at any time..
【Easy to Use】 Less I/O ports are occupied, only four - VCC, GND, SDA (serial data line), SCL (serial clock line). Address of the module: 0x27.
【Support IIC Interface】It only takes two I/O port thus saving more for other usages. You can adjust the contrast by the potentiometer at its back. If you don’t want the back light, you can also unplug the jumper cap at the LCD back..
【Widely Applications】LCD display module based on the popular controller, works great with for Arduino and other micro-controllers..

The master-slave module has three functions of transparent transmission, remote control and PIO acquisition. It can be switched and set through the AT command set. It is easy to use the same as the Bluetooth serial port module you have used before, without changing the PCB and the lower computer program..
Support AT command, users can change the serial port baud rate, device name, pairing password and other parameters as needed, use flexible..
Support UART/I2C interface, and support SPP Bluetooth serial port protocol, has the advantages of low cost, small size, low power consumption, high sensitivity of sending and receiving, etc., only need to be equipped with a few peripheral components to achieve its powerful functions..
This module is mainly used in the field of short-distance data wireless transmission. It can be easily connected to the Bluetooth device of the PC, or the data between the two modules can be intercommunicated..
When the Bluetooth connection is not established, the baud rate, name, and pairing password can be set by the AT command. After the setting, the parameter is saved after power-off, and the Bluetooth connection automatically switches to the transparent transmission mode..

The "Nokia 5110 LCD" interface has been added.
The bluetooth module interface has been added, Convenient Bluetooth wireless serial communication..
The "I2C" communication interface has been added Compatible with Arduino UNO.
