The Arduino Uno is a microcontroller board 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.
We manufactured an elegant and innovative protective case designed specifically for the Arduino Uno. The case is a two-piece injection-molded ABS enclosure that snaps together around the Arduino. It provides tough protection for the Uno while providing access to all of the board's connectors.
