Sanguinololu Features

• Small design - board is 100mm x 50mm (4" x 2") - barely an inch longer than a business card!
• Sanguino clone, Atmel's ATmega644P 
• Up to 4 Pololu (or Pololu compatible) on-board (X,Y,Z,Extruder) (A4983 without voltage regulator)
• Supports multiple power configurations

-- Logic & Motors supplied by ATX power supply (needs molex harddrive connector, and optional 4pin atx connector for additional 12v/supply voltage)

-- Motors supplied by 5mm screw terminal 7-35V

-- Logic supplied by USB bus

-- Logic supplied by optional on-board voltage regulator (molex harddrive connector cannot be installed at the same time)

-- Supports multiple communication configurations

-- FT232RL on-board for USB connectivity

-- USB2TTL header is available for FTDI cable, or BlueSMIRF bluetooth module

• 2 thermistor connectors with circuitry
• 2 N-MOSFETs for extruder/bed, or whatever
• Selectable 12v(or supply voltage)/5v endstop voltage
• Edge connectors enabling right-angle connections
• Silkscreen for connectors on both sides of the board, facilitating bottom cable connections
• 13 Extra pins available for expansion and development - 6 analog and 8 digital, with the following capabilities

-- UART1 (RX and TX)

-- I2C (SDA and SCL)

-- SPI (MOSI, MISO, SCK)

-- PWM pin (1)

-- Analog I/O (5)

All through-hole components (except FTDI chip) for easy DIY soldering.
