Metro Mini 328-5V 16Mhz

ATmega328 brains - On this popular chip 32KB flash (reserved for 1/2K bootloader), 2KB RAM, clocked 16MHz Power the METRO Mini with shielded 6-16V polarity on Vin pin or plug the micro USB connector into any 5V USB source. METRO has 20 GPIO pins, 6 of which are reserved for Analog and 2 for USB-to-serial converter. ; There are also 6 PWMs in 3 timers (1 x 16 bit, 2 x 8 bit). ; It has a hardware SPI port, hardware I2C port, and hardware UART to USB. ; The GPIO Logic level is 5V but you can easily convert it to 3.3V logic by cutting and soldering a jumper on the bottom. ; 5V onboard regulator with 150mA output, 3.3V 50mA can be used through the FTDI chip. ;
