Product Description
ADAFRUIT INDUSTRIES 2488 METRO 328 MCU Development Board is a high-quality development board built around the ATmega328 microcontroller from the SAM processor family. Operating at 16 MHz, it features 32 KB flash memory with 0.5 KB reserved for the bootloader, and 2 KB RAM, making it suitable for a wide range of embedded and educational projects.
The board provides 20 digital I/O pins, including 6 PWM outputs and 6 analog inputs, facilitating diverse interfacing options. The logic level is 5 V with 3.3 V compatible inputs, allowing easy integration with various sensors and modules.
Power can be supplied through a 7 V to 9 V DC input via the 2.1-mm DC jack with an on/off switch, or alternatively, through the 5 V micro-USB connector. The board smartly switches between USB and DC power sources as needed.
For programming and debugging, the METRO 328 uses the well-supported genuine FTDI FT231X USB interface. Headers are pre-soldered for convenience, and four rubber bumpers are included to protect the board during handling.
The compact size of 53 x 71 x 13 mm and lightweight design (19 g) make this board ideal for embedded, laboratory, educational, industrial prototyping, and hobbyist applications. It is compatible with all Adafruit shields, enhancing flexibility and modular expansions.
