Description

The Pro Mini ATMEGA328P 5V/16MHz is a compact microcontroller board based on the ATmega328, designed for applications where space and integration are paramount. Operating at 5V with a 16MHz clock, it offers robust processing capabilities for a wide range of embedded projects. This board is tailored for users who are familiar with external programming methods, as it omits on-board USB connectivity to achieve its minimal footprint and cost-effectiveness.

Featuring 14 digital input/output pins, of which 6 can be configured for PWM output, and 8 dedicated analog input ports, the Pro Mini provides ample I/O for sensor integration, actuator control, and general-purpose digital logic. Programming is achieved via a 6-pin header, which connects to an FTDI serial-to-USB adapter, facilitating seamless code uploads and serial communication through the Arduino IDE. Its pin layout maintains compatibility with the legacy Arduino Mini, making it a versatile choice for semi-permanent installations and custom hardware designs.

Key Features

  • Utilizes the ATmega328P microcontroller with a 16MHz external resonator for stable timing.
  • Ultra-thin 0.8mm PCB (33x18mm) and lightweight design (approx. 2g) for easy embedding.
  • Requires off-board USB connection via an FTDI adapter for programming and serial communication.
  • Supports auto-reset functionality for convenient code uploads from the Arduino IDE.
  • Integrated 5V regulator capable of delivering up to 150mA output, with over-current protection.
  • Flexible DC input voltage range from 5V (regulated) up to 12V (unregulated via RAW pin).
  • Equipped with on-board Power and Status LEDs for immediate operational feedback.
  • Offers 14 digital I/O pins (6 PWM capable) and 8 high-resolution analog input pins.

Applications

  • Compact embedded systems and IoT sensor nodes.
  • Robotics, drone control, and miniature automation projects.
  • Wearable electronics and portable devices where space is critical.
  • Custom hardware prototyping and semi-permanent installations.
  • Educational projects requiring an affordable and versatile microcontroller.

Frequently Asked Questions

How do I power and program the Pro Mini ATMEGA328P?

The Pro Mini requires an external FTDI Basic Breakout board or FTDI cable for both power and programming. It does not have an on-board USB interface. Connect the FTDI device's 6-pin header to the Pro Mini's corresponding pins to upload sketches via the Arduino IDE and provide 5V power.

What is the input voltage range for this board?

The Pro Mini ATMEGA328P (5V/16MHz version) has an on-board 5V regulator, allowing it to accept an unregulated DC input voltage from 7V to 12V on its RAW pin. For regulated 5V power, you can supply it directly to the VCC pin.

Is this Pro Mini compatible with standard Arduino libraries?

Yes, this board uses the ATmega328P microcontroller with the standard Arduino bootloader (like the Arduino Uno). It is fully compatible with most Arduino libraries and sketches developed for the Uno, requiring only an external FTDI programmer for code uploads and serial communication.

What is the difference between the 5V/16MHz and 3.3V/8MHz Pro Mini versions?

The 5V/16MHz version operates at a higher clock speed and requires 5V logic levels, making it suitable for standard 5V components. The 3.3V/8MHz version uses lower power and 3.3V logic, ideal for battery-powered applications and direct interfacing with 3.3V sensors without level shifters.
