The Pro Mini ATMEGA328P 3.3V/8MHz is a variant of the Arduino Pro Mini series designed to operate at a lower system voltage (3.3V) with an 8MHz bootloader. It is suitable for users who are familiar with Arduino and its limitations, including the lower voltage, lack of connectors, and the absence of onboard USB.
Key features of the Pro Mini ATMEGA328P 3.3V/8MHz include:
1. Microcontroller: Based on the ATmega328 microcontroller, the Pro Mini offers 14 digital input/output pins (6 of which can be used as PWM outputs) and 6 analog inputs.
2. Operating Voltage: The board operates at a lower system voltage of 3.3V, making it suitable for applications where lower power consumption is a priority.
3. On-Board Resonator: It comes with an on-board resonator, eliminating the need for an external oscillator.
4. Reset Button: Equipped with a reset button for convenient manual resets.
5. Flexible Power Options: Can be powered through a variety of sources, and a six-pin header allows connection to an FTDI cable for USB power and communication.
6. Headers for Connectors: The board comes with headers, providing flexibility for using various types of connectors or direct soldering of wires. The pin layout is compatible with the Mini Arduino.
7. Semi-Permanent Installation: Designed for semi-permanent installations in objects or exhibitions, where a compact and reliable microcontroller is needed.
This Pro Mini variant offers a compact and versatile solution for projects that require a lower system voltage and can benefit from its smaller size and reduced power consumption. It’s particularly suitable for applications where space constraints and power efficiency are essential considerations.
