Atmega328 Arduino Board 3.3V - 5V

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.  It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. 

 Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.  The microcontroller on the board is programmed using the Arduinoprogramming language (based on Wiring) and the Arduino development environment (based on Processing).  Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g. Flash, Processing, MaxMSP).

This board is based on Arduino Duemilanove bootloader with optional jumper to run with 5V or 3.3V.

Features: 

• With FT232RL USB UART bridge.
• Jumper to configure this board into Arduino ISP programmer.
• Jumper to change supply between 5V or 3.3V when external power supply is connected.
• Rugged PCB for robotic application.
• 5/3.3Volts internal operation (9V external supply).
• Reverse polarity protected input.
• With FT232RL USB to UART.
• Compatible with most Arduino shield.
• 16 MHz crystal.
• Optimally placed Tx & Rx LEDs.
• The Board can power the programming device or vice-versa.
• Can also be programmed by STK500 / AVR ISP (6 pin header).
• Arduino auto reset can be disabled.
• The power source can be switched manually from USB to external 9V input.
