1. Introduction of Arduino Shield
Arduino UNO Easy Shield is an extended board for Arduino UNO and Arduino-compatible boards. The product supports 2 ATCBus sockets that allow users to connect the Easy Board with Arduino UNO quickly and easily to perform applications such as GSM, GPS, Wifi, Bluetooth, etc. In addition, board support "Switch" allows the program to load Arduino without removing the board mounted on the shield. Also, with the same size as the Arduino UNO, handy data output, the Arduino UNO Easy Shield brings subtle inspiration when combined with the Arduino and Easy Board.
3. Feature of Arduino Shield
Into provide convenience for users, on Arduino UNO Easy Shield has integrated 2 ATCBus sockets to provide users convenience when combining Arduino with easy board.
With the Arduino UNO Easy Shield you can connect the Arduino UNO to all your Easy boards to make applications such as GSM, GPS, Wifi, Bluetooth, etc.
Arduino UNO Easy Shield is power supply from Arduino UNO board power pins.
On the Arduino UNO Easy Shield is integrated AMS1117-3.3 IC stabilized 3.3V voltage from the Vin input voltage and can raise the current load for this voltage up to 1A to help Arduino board perform some applications need high current at 3.3V logic.
On the Arduino UNO Easy Shield, a switch is selected between the program load mode for the microcontroller on the Arduino and the UART mode for easy board.
When you need to load the program for the Arduino, the user switches the "Switch" to the position 1 (PROG).
When you need to use Arduino's UART pins to run the application, the user switches the "Switch" to position 2 (UART).
On the Arduino UNO Easy Shield with integrated voltage isolation helps ensure safety for Arduino when UART communication with easy boards has 5V voltage.
Ngoài ra người dùng cũng có thể giao tiếp trực tiếp UART giữa Arduino và các easy board bằng cách nối liền Jumper như hình dưới.
Combined With Peripherals
With the integration of 2 ATCBus on the user board can easily be combined with other devices in the ATCBus system
