Overview
Iteaduino Uno is a microcontroller board based on the Arduino UNO. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
Features
- New external IO pin map
- Efficient DC-DC Power supply with wide range input
- 3.3V/5V Operating Voltage selection
- All pins out for Sensor and Servo
- UART/IIC interface breakout

Power
The Iteaduino Uno can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.
The board can operate on an external supply of 7 to 23 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable.
Power supply select switch:
Iteaduino UNO iteadstudio.com 2012-11-11 4 Tech Support: support@iteadstudio.com On Iteaduino UNO board, there is a supply power select switch for selecting the 3.3/5V power supply. Much compatible shields can be plug in Iteaduino UNO board.
The power pins are as follows:
- VIN. The input voltage to the Iteaduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
- 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
- 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 500 mA.
- GND. Ground pins.
