Product Details

The Arduino Uno R3 is a microcontroller board that is based on the ATmega328P chip used mostly for development and prototyping. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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. You can tinker with your Arduino UNO R3 without worrying too much about doing something wrong, in the worst-case scenario you can replace the chip and start over again.

You can download the IDE software for free on the Arduino official website.

This board is a 100% identical clone and not the original Arduino Uno.
