Arduino Pro Mini ATMega328p Dev Board
Arduino Pro Mini ATMega328p Dev Board overview
The Arduino Pro Mini ATMega328p Dev Board is an electronic component. Main ratings: Controller ATmega328P; Clock frequency 16 MHz; Operating voltage 5V; Maximum voltage 5-12V. This page brings together the Arduino Pro Mini ATMega328p Dev Board pinout and key specifications, with the full datasheet PDF to preview below or download.
Arduino Pro Mini is a microcontroller based on the Atmega328p microprocessor. The heart of the Arduino PRO Mini is the ATmega328P microcontroller, which operates from a base 5-volt standard for most ARDUINO boards and at a quartz resonator frequency of 16 megahertz, which has also proven itself well in the UNO board, widely known to the ARDUINO community.
Arduino Pro mini is intended for semi-permanent installation in objects or exhibitions. The board comeswithout pre-mounted headers, allowing the use of various types of connectors or direct soldering ofwires. The pin layout is compatible with Arduino shields. The 3.3V versions of the Pro can be poweredwith a battery.
