Adafruit sure love the ATmega328 here at Adafruit, and Adafruit use them a lot for Adafruit's 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 Adafruit need to go small, Adafruit use a Pro Trinket 3V or 5V, but if you want to have USB-to-Serial built in, Adafruit reach for an Adafruit METRO Mini.

METRO Mini is the culmination of years of playing with AVRs: Adafruit 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 SiLabs CP2104 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. Once headers are installed they can be fitted into 0.6" wide sockets

Mac & Windows People! Don't forget to grab & install the FTDI VCP drivers from FTDI and the SiLabs CP210x drivers from SiLabs to make the COM/Serial port show up right! The default drivers may not support the interface chip!
