UNO R3 DIP AVR USB Development board is an open-source microcontroller board based on the ATmega328 microcontroller chip. It has 14 digital input/output pins (of which 6 provide PWM output) and 6 analog input/output pins and has onboard 16 MHz ceramic resonators, USB port, ICSP header and a microcontroller reset button. It can be easily conntected to a computer with a USB cable or a DC adapter or a battery to get it running. While the UNO can be powered via the USB connection or with an external power supply, the power source is selected automatically.
