arduino uno r3 microcontroller a000066 datasheet

The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino Uno can be powered via the USB connection or with an external power supply. The ATmega328 on the Arduino Uno comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer.

For details, see the reference and tutorials. Select 'Arduino Uno from the Tools > Board menu (according to the microcontroller on your board). The Arduino Uno can be programmed with the Arduino software. The board can operate on an external supply of 6 to 20 volts. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1 mm center-positive plug into the board's power jack.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The power source is selected automatically. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. 'Uno' means one in Italian and is named to mark the upcoming release of Arduino 1.0. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. The Arduino Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. It contains everything needed to support the microcontroller simply connect it to a computer with a 1.5m USB Cable Type A to B or power it with a Wall Adapter Power Supply - 9VDC 650mA or DFRobot 7.4V Lipo 2500mAh Battery (Arduino Power Jack) to get started.

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. The Arduino Uno is a microcontroller board based on the ATmega328 microchip.

Based on the ATmega328 (removable DIP IC).
