This Arduino Uno is an original microcontroller board from Arduino officials based on the ATmega328P.  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 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.

“Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Original Arduino Uno Rev3 board is the first in a series of USB Arduino boards and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.



Getting Started

You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics.

    A very good And Perfect board for beginners. Better than esp32 in terms of learning as unlike esp32, it’s pins are not jumbled. The product quality upon delivery was also perfect. I’ve been using this board with a case that I ordered from robu for the pas year and this board has never failed me once. It’s much better than the fake clones which can at any moment of time just stop working. 10/10 would recommend

    Excellent service & products . I had ordered original Arduino & got exactly original Arduino. I had requested an early shipment as I was to leave for out of station, & surprisingly I received the items the very next working day. I couldn’t believe it . That too from Pune to Kolkata.
    Fantastic customer support.
