Description

The Adafruit METRO Mini 328 lets you make your Arduino-based project tiny. Recently Adafruit had to redesign this board to move from the obsolete CP2104 to the available CP2102N, and one thing led to another, and before you know it they made a completely refreshed design: the Adafruit METRO Mini 328 V2.

The V2 is a significant redesign, enough, so it's considered a completely new product. It still features the ATmega328 chip and is drop-in compatible with the original METRO Mini, but has many upgrades and improvements:

  • Same ATmega328 chip, running at 16 MHz, which makes it compatible with all Arduino UNO based libraries, codes and examples
  • Same pinout and size, same mounting hole locations - drop-in compatible!
  • Additional STEMMA QT port for plug and play I2C connections
  • USB Type C port instead of Micro B
  • Upgraded USB to serial converter from CP2104 to CP2102 - same great reliable drivers!
  • Can still be set to use 3.3V power and logic by soldering a jumper on the bottom.

The METRO Mini V2 works great with the Arduino IDE, and runs the ATmega328P at 16MHz so it is pin-compatible with Arduino UNO R3 - note you won't be able to plug in shields, but great for use with breadboards. You can use this with the Arduino IDE (both desktop and cloud version) by selecting 'Arduino UNO' in the Boards menu.

Features

  • 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, separate 3.3V 500mA regulator is also available.
  • USB to Serial converter, there's a genuine SiLabs CP2102N 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
  • USB C power and data
  • 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.

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