The Uno R3 is an open-source microcontroller board built around the ATmega328 chip. It features 14 digital input/output pins, 6 analog input pins, a 16 MHz ceramic resonator, a USB port, an onboard DC power jack, an ICSP header, and a reset button. This board provides everything necessary to support the microcontroller. To use it, simply connect it to a computer via USB or power it with a DC adapter or battery.

Unlike previous versions, the Uno R3 does not rely on the FTDI USB-to-serial driver chip. Instead, it incorporates the Atmega16U2 (or Atmega8U2 up to version R2) programmed as a USB-to-serial converter. The Uno can be powered through USB or an external power supply, with automatic switching between sources.

External power can be provided via an AC-to-DC adapter (wall-wart) connected through a 2.1mm center-positive plug or by inserting battery leads into the Gnd and Vin pin headers. The board operates on an external supply ranging from 6 to 20 volts. However, if supplied with less than 7V, the 5V pin may deliver less than five volts, potentially causing instability. Powering with more than 12V may overheat the voltage regulator and damage the board. The recommended voltage range for optimal performance is 5V to 12V.
