The Arduino UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.

This is a clone board of the original Arduino Uno SMD Rev3 board that uses the same microcontroller (ATmega328P). This board is Arduino-Compatible, which means that you can use it the same way you use the original Arduino Uno, but with a much cheaper price! This boards uses an CH340 instead of the ATmega16U2 found on the Arduino Uno (or the FTDI found on previous generations).

The Arduino Uno Rev3 SMD is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, 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.
