Description
Xboard is a board compatible with Arduino, has an Ethernet port, slot for XBee modules and Atmega328 microcontroller known from version Uno. The device can be programmed via the Arduino IDE using an FTDI converter (similarly to the popularArduino Mini). Xboard gives you the ability to quickly connectany project to the Internet. The module is particularly useful for creation of home automation devices.
The board contains an ATmega328 microcontroller operating with voltages of 5 V. It has 8 digital inputs/outputs, 4 of which can be used as PWM outputs (e.g. for motor control) and 8 as analog inputs. The system works with the clock signal with the frequency of 16 MHz. The module also has USB connector that is used to power Xboard, RESET button, and the leads used to connectthe AVR programmer.
XBoard v2 of the Internet-bridge - compatible with Arduino.

In order to start DFRduino, you need to connect the system to the computer usingthe FTDI converterand selectthe Arduino IDE and the Arduino Uno. |
Power
The module can be powered via mini USB cable(5 V voltage) and an external device, for example, the AC adapter, the battery or the rechargeable battery (with a voltage of 5 V - 12 V). Rechargeable battery or other source is connected to the battery slot.
Programming
Creating and installing software is allowed by the free environment of the Arduino IDE. Implemented boot loader allows you to send the program via USB cable usingan FTDI converter connected to RX and TXpins of the board. A detailed description can be found inthe tutorial.

The mini-usb slot is only used for powering the board using voltage of 5 V. To program the system,it is necessary to apply the FTDIconverter. |
