ADAFRUIT INDUSTRIES METRO Mini 328 MCU Development Board 5 V, 16 MHz, ATmega328 Microcontroller 2590

ADAFRUIT INDUSTRIES 2590 METRO Mini 328 MCU Development Board is a professional-grade microcontroller development board designed for educational, prototyping, and embedded system projects. Featuring the ATmega328 microcontroller running at a 16 MHz clock speed with 5 V logic levels, this compact board offers reliable performance and compatibility with the extensive Arduino UNO ecosystem.

The METRO Mini 328 provides 20 digital input/output pins, of which 6 support PWM output and 6 channels are available as analog inputs, making it highly versatile for interfacing sensors, actuators, and other peripherals. Power can be supplied via a DC input ranging from 6 V to 16 V or through a 5 V micro-USB connector with automatic power source switching, simplifying deployment in various setups.

USB programming and debugging are facilitated by the genuine FTDI FT231X interface, widely supported across operating systems. The board includes 32 KB of flash memory with 0.5 KB reserved for the bootloader, and 2 KB of RAM to support complex program operations.

Its compact dimensions of 53 x 71 x 13 mm and lightweight 19 g make it ideal for embedded applications where space and weight are critical. The board comes supplied with 4 rubber bumpers for physical protection during installation and transport. The device complies with RoHS standards, promoting environmentally friendly manufacturing and reduced hazardous substances.

The METRO Mini 328 supports 5 V logic but also is compatible with 3.3 V input levels, enabling a wider range of peripheral compatibility. This product is recommended for STEM education, prototyping, hobby projects, and small-scale industrial development requiring a low-power, efficient MCU platform.

The board integrates an ATmega328 microcontroller running at 16 MHz with 32 KB flash memory. Compatible with Arduino UNO projects and ecosystems for software and hardware flexibility. Provides 20 digital I/O pins including PWM and analog inputs for extensive interfacing.

Power supply via 6 - 16 V DC input or USB micro-USB connector with auto switch. USB programming and debugging facilitated by FTDI FT231X interface. Compact form factor at 53 x 71 x 13 mm and ultra-lightweight of 19 grams.

Includes 4 rubber bumpers for protection and mechanical stability. RoHS compliance ensures environmentally safe product standards. Ideal for industrial controls, development tools, STEM education, and prototype designs.
