Uno R3 for Arduino


Uno is the first Arduino board to be released marking the Arduino Software (IDE) 1.0 and is the reference board for the Arduino platforms.

This board is a simple board for your project needs, coming out with 14 digital input/output pins with 6 PWM and 6 analog inputs ensures you a decent amount of devices for your project.

The Uno can be powered with the included USB cable, or through the DC Barrel Connector to a 9V battery or wall socket supply.

We sell two variants of the Uno:

  1. CH340G – which comes at a lower price but requires a third-party driver (See this guide: CH340), and
  2. ATmega16U2 – which allows a plug-and-play use of the Uno.
