Power
- the Uno R3 can be powered via the USB connection or with an external power supply. The power source is selected automatically.
Memory
- the ATmega328 has 32 KB (with 0.5 KB used for the bootloader) flash memory. It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library).
Input and Output
- each of the 14 digital pins on the Uno can be used as an input or output. They operate at 5 volts. Each pin can provide or receive a maximum of 40mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
Communication
- the ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual COM port to software on the computer.
Automatic (software) Reset
- rather than requiring a physical press of the Reset button before an upload, the Uno R3 is designed in a way that allows it to be reset by software running on a connected computer.
USB Overcurrent Protection
- the Uno R3 has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.
