If you know Arduino's you know that many of the related products are pen sourced hardware device. This means that reference files and designs are freely provided. This means that high quality boards can be made using similar parts, quality, functionality, and compatibility as the official released boards. Often  these designs are enhanced or modified for additional flexibility. The Arduino Pro Mini was originally designed and manufactured by SparkFun Electronics, the source files were freely distributed. These boards are based on those designs but have relocated A6 and A7 to the bottom edge for easier access and have also added an extra ground connector for more flexibility.

What is an Arduino Pro Mini:

The Arduino Pro Mini is a microcontroller board based on the ATmega328. 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 or use the corresponding connections with any other USB to TTL converter.

The Arduino Pro Mini is intended for semi-permanent installation in your projects. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.

This version of the Pro Mini runs at 3.3V and 8 MHz.
