Description of πŸ”Œ Adafruit 5V 16MHz Metro Mini 328

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. 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. 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

Easily converts from 5v to 3.3v

There is a solder jumper on the bottom to convert it to a 3.3v system For some reason Adafruit doesn't advertise this ability very well .

Pros
  • Good product for the price
Cons
  • Crumpled packaging

Great board from Adafruit.

This is a really nice little board. Works great, very smooth and fast. My project has been greatly improved due to its size and features.

Pros
  • Large selection
Cons
  • Not as good as it says

These are by far my favorite Arduino boards

These are by far my favorite Arduino boards! They have all the features of the Uno but are only about 20% the size. The LEDs are bright and are great for monitoring activity on the board. It all just screams quality to be expected from Adafruit. I use the Metro Mini for each of my projects unless an absolute minimum size is required. In this case I'm using an Attiny85 based board of my own design. I don't even have other boards handy anymore as this one covers all the bases.

Pros
  • Outstanding design
Cons
  • No instructions

Great support for beginners, high quality board

The low cost and flexibility of this version of Arduino combined with Adafruit's incredible support documentation, community, and product quality make it a great choice for little ones projects and beginners.

Pros
  • Always liked
Cons
  • No form required

Metro Mini > Nano for computers and accessories

This is 2016 updated version with CP2104 chip. It does everything the old FTDI Mini/Nano did and even better. This solves the problems that older nano knockoffs had with FTDI driver detection. Monitors the USB to serial port like any Arduino. It has the same form factor as Nano but 1 pin shorter. If you have an old nano breakout board, it's 100% compatible, but the labels are different. Don't forget to download and install (FTDI VCP driver by FTDI) and (SiLabs CP210x driver by SiLabs) for the…
