Hi
I was wondering what I/O this board supports. Is there a schematic for this? If so, where can I find it?
I am not familiar with the Arduino chips.
Thanks

Re: Menta schematic
The Adruino is a combination of hardware and firmware. The hardware is a fairly simple development board for the Atmel ATMega328 microcontroller with support for a direct USB connection to a computer. The firmware is a bootloader that allows the '328 to load programs through serial I/O and run them when the chip starts up.
The chip itself has 23 general-purpose I/O pins that can be configured for digital input, output, or tristated. There are 8 pins that connect to a multiplexed 10-bit ADC. There are also internal registers that let you use groups of pins for SPI, 2-wire, and USART.
The datasheet for the chip itself lives here: http://www.atmel.com/Images/doc8161.pdf
and there's a lot of reference information at the Arduino website: http://www.arduino.cc
