      • We sure love the ATmega328 here at Adafruit, and we use them a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Pro Trinket 3V or 5V, but if you want to have USB-to-Serial built in, we reach for an Adafruit METRO Mini.

        METRO Mini is the culmination of years of playing with AVRs: we wanted to make a tiny, breadboard-friendly development board that is easy to use and is hacker friendly. Metro Mini can be programmed with the Arduino IDE (select 'UNO' in the boards dropdown)

        • ATmega328 brains - This popular chip has 32KB of flash (1/2 K is reserved for the bootloader), 2KB of RAM, clocked at 16MHz
        • Power the METRO Mini with 6-16V polarity protected on the Vin pin, or plug the micro USB connector to any 5V USB source.
        • METRO has 20 GPIO pins, 6 of which are Analog in as well, and 2 of which are reserved for the USB-serial converter. There's also 6 PWMs available on 3 timers (1 x 16-bit, 2 x 8-bit). There's a hardware SPI port, hardware I2C port and hardware UART to USB.
        • GPIO Logic level is 5V but by cutting and soldering closed a jumper on the bottom, you can easily convert it to 3.3V logic
        • 5V onboard regulator with 150mA out, 3.3V 50mA available via FTDI chip
        • USB to Serial converter, there's a genuine FTDI hardware USB to Serial converter that can be used by any computer to listen/send data to the METRO, and can also be used to launch and update code via the bootloader
        • Four indicator LEDs, on the top of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for the UART, and a red LED connected to pin PB5 / digital #13
        • Easy reprogramming, comes pre-loaded with the Optiboot bootloader
        • Beautiful styling by PaintYourDragon and Bruce Yan, in Adafruit Black with gold plated pads.

        The Metro Mini comes as a fully assembled and tested board, with bootloader burned in and also a stick of 0.1" header. Some light soldering is required if you'd like to plug it into a breadboard, or you can solder wires or header directly to the breakout pads.

        • ATmega328 microcontroller with Optiboot (UNO) Bootloader
        • USB Programming and debugging via the well-supported genuine FTDI FT231X
        • Input voltage (Vin): 6-16V (a 9VDC power supply is recommended)
        • 5V logic with 3.3V compatible inputs, can be converted to 3.3V logic operation
        • 20 Digital I/O Pins: 6 are also PWM outputs and 6 are also Analog Inputs
        • 32KB Flash Memory - 0.5K for bootloader, 31.5KB available after bootloading
        • 16MHz Clock Speed
        • Adafruit Black PCB with gold plate on pads
        • 18mm x 44mm x 4mm / 0.7" x 1.7" x 0.2"
        • Weight: 3g
        • Derivative of "Arduino UNO R3 Reference design" 
        • Open source hardware files on github!
