If you are interested in boards with similar functionality, at Arduino you can find: The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. 'Uno' means 'One' in Italian and is named to mark the upcoming release of Arduino 1.0. 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 allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.ATmega16U2 instead 8U2 as USB-to-Serial converter.The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.Īdditional features coming with the R3 version are: 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. 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. The Arduino Uno Rev3 SMD is a microcontroller board based on the ATmega328.
