Description
The Uno r3 is a microcontroller board based on the ATmega328 chip from MicroChip. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16MHx crystal oscillator, a USB type B connection, a DC power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with USB cable or power it with an AC-to-DC adapter (you’ll need one with a standard 5.5mm DC Barrel Jack Connection) or battery to get started. This is the latest revision of Uno and features stronger reset circuit and 16U2 microcontroller instead of the 8U2.
Included:
1x Uno Compatible R3 Board
1x USB cable
Features:
- Microcontroller: ATmega328 (Datasheet)
- Operating Voltage: 5V
- Input voltage (limits): 6-20V
- Digital I/O pins: 14 (of which 6 provide PWM output)
- Analogue Input Pins: 6
- DC Current per I/O Pin: 40 mA
- DC Current for 3.3V Pin: 50mA

Notes:
The USB to serial conversion chip is an Atmel MEGA16U2 which is the same microcontroller as the original Arduino Uno.
