Description

• Digital I/O Digital inputs/outputs were:0~13
• Analog I/O Analog input/output: 0~5; Support ISP download function
• The input voltage: when connected to the computer USB without external power supply
• External power supply 7 v to 12 v dc input voltage
• Output voltage: 3.3 V and 5 V dc voltage output dc voltage output.

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). 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. 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.. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
