Features and Construction

This microcontroller board incorporates specific technical specifications that define its capabilities and implementation parameters. The documented features provide clear guidance for integration into electronic systems without requiring interpretation of unspecified performance characteristics.

Material and Build

The board utilises an Atmel Atmega328P-AU microcontroller as its central processing unit, accompanied by a 16MHz resonator that establishes the operational timing reference. Physical construction includes mounting hole pin headers that facilitate secure installation within project enclosures or on prototyping surfaces. A reset button provides manual control over the microcontroller's operation cycle, while the TTL level serial port transceiver (RX/TX) enables standard serial communication protocols. The board's material composition follows typical printed circuit board manufacturing with copper traces connecting the various components according to the specified pin configurations.

Size and Practical Fit

With dimensions of 33.3mm by 18.0mm, the Mini Pro board occupies minimal space within electronic assemblies. This compact footprint allows incorporation into smaller projects where board area represents a limiting factor, such as wearable electronics, compact robotics, or embedded monitoring systems. The mounting hole pin headers provide physical attachment points that help secure the board during operation, particularly in applications subject to movement or vibration. The size specification ensures compatibility with standard electronic building block systems while maintaining access to all documented input/output connections.

Uses and Placement

The technical specifications of this microcontroller board support its application across various electronic prototyping and development scenarios. The combination of digital and analogue connectivity with processing capabilities enables implementation in both educational and professional contexts.

Event or Professional Use

For professional applications, the board's 14 digital input/output ports (including six PWM-capable outputs) support control of multiple actuators, relays, or communication modules simultaneously. The eight analogue inputs facilitate data acquisition from sensors measuring temperature, light intensity, pressure, or other environmental variables. Support for external DC power supplies ranging from 3.3V to 12V, including 9V battery options, provides flexibility in power source selection for field deployments or portable installations. These specifications make the board suitable for industrial monitoring systems, prototype development, or embedded control applications where documented capabilities match project requirements.

Everyday Home Use

In home electronics projects, the board's serial download capability allows programming via standard computer interfaces for hobbyist applications. The digital and analogue pins can connect to common components like LEDs, buttons, potentiometers, or basic sensors for automation systems, interactive displays, or educational demonstrations. The compact size facilitates integration into enclosure-constrained projects such as custom controllers, environmental monitors, or small robotics. With support for battery power, the board can operate in portable applications without requiring continuous mains connection, suitable for temporary installations or mobile projects.

Benefits and Buying Value
