Arduino Uno Rev 3 is a microcontroller board based on the ATmega328, an 8-bit microcontroller with 32KB of Flash memory and 2KB of RAM. 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.
Arduino Uno Rev 3 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.The Uno board is the first in a series of USB boards and it is the reference model for the Arduino platform.
Arduino Uno Rev 3 is the ideal board for getting started with electronics, through fun and engaging hands-on projects. This board is one of the best entry to the unique Arduino experience and an essential tool for your rapid prototyping needs. Uno Rev 3 is perfect for learning the basics of how sensors and actuators work. Arduino Uno is the first in a series of USB-based Arduino boards.
In terms of Arduino products, we provide many Arduino boards such as Arduino Uno, Arduino Mega, etc. Besides, there are also many extension boards based on the Arduino platform such as Seeeduino Boards. In order to be compatible with our Grove system, we have released many shields for Arduino or Seeeduino which includes Grove interface to connect the boards and Grove modules easily without jump wires.
You can use Base Shield to extend the possibilities of Arduino Uno R3 with over 300 Grove modules and sensors.
