The Arduino Pro Mini is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz quartz crystal. The board is designed for use with the Arduino IDE, and can be powered by an external power supply or by USB. The board also comes in a 3.3V variant which uses the same ATmega328P but with a different voltage.
One important feature of the Pro Mini is its small size, which makes it ideal for use in projects where space is at a premium. Additionally, it uses the standard Arduino pinout, making it easy to use with a wide variety of shields and other accessories.
The board can be programmed using the Arduino IDE and is compatible with most libraries and sketches designed for the Arduino platform.
The 5V version of the Pro Mini is powered by a voltage of 5V, which is the standard voltage level used by most electronic devices. This voltage level is compatible with most sensors and modules that can be used with the Arduino platform, making it a versatile board for a wide range of projects.
You can use a variety of programming method for the board; such as via FTDI or via ICSP header.
The PRO MINI is a small microcontroller board based on the ATmega328, intended for use on breadboards and when space is at a premium. It 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. 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
