.The Arduino Mini is a small microcontroller board intended for use on breadboards and when space is at a premium. The revision 05 has a new package for the ATmega328 (datasheet), which enables all components to be on the top of the board.
he Arduino Mini 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 USB Serial adapter or other USB or RS232 to TTL serial adapter.
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 2 KB
EEPROM 1 KB
Clock Speed 16 MHz
