The Arduino Uno SMD is a rendition of the Arduino Uno, however utilizes a surface mount variant of the Atmega328P rather than the through-opening form. This form was made because of a deficiency in supply of the through-opening Atmega328P. The board depends on the ATmega328 (datasheet). It has 14 advanced information/yield pins (of which 6 can be utilized as PWM yields), 6 simple data sources, a 16 MHz precious stone oscillator, a USB association, a force jack, an ICSP header, and a reset button. It contains all that expected to help the microcontroller; just associate it’s anything but a PC with a USB link or force it’s anything but an AC-to-DC connector or battery to begin.
The Uno varies from all former sheets in that it doesn’t utilize the FTDI USB-to-chronic driver chip. All things considered, it includes the Atmega8U2 customized as a USB-to-chronic converter.
