Arduino Uno REV3 SMD

Description Arduino Uno REV3 SMD microcontroller board ATmega328 soldered (not removable) 14 digital I/O pins (6  PWM outputs), 6 analog inputs Features an ICSP header, a 16 MHz crystal oscillator, a power jack, etc. Provides an ATmega16U2 instead of an 8U2 as USB-to-Serial converter 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 crystal oscillator, 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 an AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allows t
