The Arduino Mini 05 is a very compact version of the Arduino Nano without an on-board USB to Serial connection
WOULD YOU LIKE TO BUY AN Arduino MINI 05?
The new Mini (revision 05) has a new package for the ATmega328, which enables all components to be on the top of the board. It also has an onboard reset button. The new version has the same pin configuration as revision 04.
Warning: Don't power the Arduino mini with more than 9 volts, or plug the power in backwards: you'll probably kill it.

Input and Output
The Mini has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). Inputs 0 to 3 are broken out onto pins; input 4 to 7 require soldering into the provided holes. By default the analog inputs measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and some low-level code.
To program the Arduino Mini, you will need a USB Serial adapter or other USB or RS232 to TTL serial adapter.
The ATmega328 on the Arduino Mini comes preburned with a bootloader that allows you to upload new code to it without the use of an in-system-programmer. The bootloader communicates using the original STK500 protocol (reference, C header files).
You can also bypass the bootloader and program the ATmega328 with ICSP (In-Circuit Serial Programming).
