Adafruit Metro Mini 328 - 5V 16MHz

Make your Arduino-based project tiny and with the Adafruit METRO Mini! The METRO Mini 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. 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-
