Description
Arduino Uno R3 Compatible
Arduino Uno R3 is a microcontroller board based on the ATmega328P. It features 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 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. Due to the low-cost, you can tinker with your UNO without worrying too much about doing something wrong.

Considerations
ATmega328P devices use 3.3v logic levels, unlike other devices which may use 5v logic levels. For this reason, when interfacing to other devices which will drive your Arduino Uno R3 board. A simple voltage divider circuit is all that is required.
Setup and Configuration
The Arduino Uno R3 from SRS has a set of drivers which ensures compatibility. We have created a Setup and Installation Guide for reference which includes links to the Arduino IDE (Integrated Development Environment) along with drivers.
