-This is Pro Mini 5V/16MHz is a 3.3V Arduino running the 8MHz bootloader.
-Pro Mini ATMEGA328P come without connectors.
-We recommend the first time Arduino users start with the Uno R3.
-It’s a great board that will get you up and running quickly.
-The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off-board.
-The Pro Mini is a microcontroller board base on the ATmega328P.
-It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers.
-A six pin header can be connected to an FTDI cable to provide USB power and communication to the board.
-The Pro Mini Arduino is intended for semi-permanent installation in objects or exhibitions.
-The pin layout is compatible with the Mini Arduino.
-There are two versions of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.
