Overview:

The Arduino Mini is a small microcontroller board based on the ATmega328, intended for use on breadboards and when space is at a premium. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz crystal oscillator. It can be programmed with the Mini USB adapter or other USB or RS232 to TTL serial adapter.

Specifications:

• Microcontroller:  ATmega328
• Operating Voltage:  5V
• Input Voltage:  7-9 V*
• Digital I/O Pins:  14 (of which 6 provide PWM output)
• Analog Input Pins:  8 (of which 4 are broken out onto pins)
• DC Current per I/O Pin:  40 mA
• Flash Memory:  32 KB (of which 2 KB used by bootloader)
• SRAM:  1 KB
• EEPROM:  1 KB
• Clock Speed:  16 MHz
• Dimensions:  30 x 18mm
  

*(Warning: Don't power the Arduino mini with more than 9 volts, or plug the power in backwards: you'll probably kill it.)
