Iteaduino

Note

--> What's the different between Iteaduino and Itaduino UNO?  Iteaduino the FTDI USB-to-serial driver chip and not the Atmega8U28 programmed as a USB-to-serial converter, and Iteaduino use the Duemilanove bootloader instead of the UNO bootloader. So you need to choose the "Arduino Duemilanove or Nano w/ ATmega328" under the "Tools"->"Board" memu but not the "Arduino UNO".

Overview

Iteaduino is an Arduino compatible board. It’s designed is basing on Arduino UNO/Duemilanove, 100% compatible with its existing program and shields,  and with much practical improvement. The power consumption is about 50% of  the original Arduino boards. Support both 3.3v and 5v operation level.

Basic features

• Inherits all of Arduino Duemilanove features.
• Compatible with Arduino UNO/Duemilanove pins, holes and dimensions.
• 3.3V/5V Operating Voltage selection
• More visible location of Indicator LEDs
• Wide range external power supply from 7~23V DC
• All pins out for Sensor and Servo
• UART/IIC interface breakout

What are the changes from Arduino to Iteaduino

1. Wider power supply range to 23V, and higher conversion efficiency
2. 3.3V Operating Voltage selection to easier connect with 3.3V device 
3. Easier access to reset button
4. More visible location for LEDs for Power , RX and TX.
5. Sensor and Servo/Digital interface break out
6. Re-route PCB for analog/digital part
7. Mini USB socket for fixing more shield

Hardware

Digital Interface: D0~D13 pin

Analog Interface: A0 A1 A2 A3 A4 A5 pin

Because of the DC-DC power supply design, it will povide higher conversion effciency than the LDO chip on original Arduino boards, it will save 50% power consumption, especially in the high-current power supply.

Iteaduino has all pins broken out, so it can be connected to the servo and Electronic/ Sensor Brick by the 3PIN cable directly, you don't need the shields as an adaptor.

Iteaduino can work in both 5V and 3.3V by the operation level switch, so you can use Iteaduino to connect with 3.3V level device directly , which the original Arduino boards can not.

Both IIC and UART pins breakout, easier for prototype connection.
