UNO R3 Original Arduino Board

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Arduino Uno is the ideal board for getting started with electronics, through fun and engaging hands-on projects. This board is your entry to the unique Arduino experience: great for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs. Arduino Uno Rev3 is the most used and documented board in the Arduino family.

The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM
