Pro Mini is a compact yet powerful development Board. It works on the same ATmega328 microcontroller like UNO but is the only 1/3rd of the size of UNO. The size is reduced by removing an in-built programmer and the USB port, so pro mini requires an external programmer like an FTDI board to program it. The small size enables the board to be used on a PCB and other final applications.

Apart from the size, the specification of pro mini (5V) and UNO are almost similar and hence they both can exchange the same program.

Note: This version of Pro mini is 5V
