Adafruit METRO 328 without Headers

The Adafruit METRO development board is designed for flexibility and ease of use, powered by the robust ATmega328 processor. It features 32KB of flash memory and 2KB of RAM, clocked at 16MHz, making it ideal for a wide range of projects.

With 20 GPIO pins, including 6 analog inputs, this board caters to the needs of diverse electronic tasks. It provides 6 PWM outputs on 3 separate timers (1 x 16-bit, 2 x 8-bit), ensuring precise control over your components. The METRO also supports USB to Serial conversion, essential for reliable communication with connected devices. Users can seamlessly transition between 5V and 3.3V logic levels by modifying a simple solder jumper.

Power options include a 7-9V DC input or a micro USB connection to any 5V source. An on-board switch allows easy power management. Automatic switching between USB and DC input keeps your project running smoothly and efficiently.

The METRO is equipped with four indicator LEDs for straightforward debugging, and the board comes with the Optiboot bootloader pre-installed, facilitating easy code updates. Its stylish design, with black paint and gold-plated pads, ensures compatibility with all Adafruit shields.

Supplied fully assembled and tested, the METRO arrives sans headers or DC jack, offering customization flexibility. Solder wires or headers directly to breakout pads as needed, and enjoy four rubber bumpers to ensure stability during use.

Ensure correct functionality on Mac and Windows by installing FTDI VCP drivers. Adafruit's METRO makes your electronics projects straightforward and a breeze to manage.
