12V / 24V Arduino Circuit Board , Arduino Compatible Board 64K

This board is the brains behind the Generation 3 Electronics.

The heart is a Sanguino which is an Ardu-compatible board

that is powered by an ATMEGA644P chip.

It has connectors to hook up all the various peripherals that

you'll need to drive a RepRap machine. It has headers for

three stepper drivers, as well as 4 RJ45 connectors for Extruder

Controller Boards. Not only that, but it has an SD card and a

connector to hook it up to an ATX power supply

I2C headers for simple hookup of external peripherals. On/Off switch for instant-kill and simple control of the entire

system. Onboard atmega644p - 64K flash space, 4k ram, 32 I/O pins,

Ardu compatible.Built-in

SD card socket for printing from file and buffering large

print jobs.RS485 connection for noise-free communications with extruder / toolhead controllers. ATX power connector for power. It can also turn the power

supply on and off. 3 x Stepper driver connectors with min/max inputs. Headers to allow existing Sanguinos to plug straight in.
