This is the MakerBot MightyBoard, a revolution in 3D Printer Control Technology. Use it to power your MakerBot Replicator 3D Printer. Here are just a few things the MightyBoard can do: control up to 5 stepper motors with BotStep Stepper Controllers, control up to two extruders (with heater cartridges, safety thermostats, thermocouples, and fans), control the Replicator Interface Board, connect to up to 6 endstops, control RGB LED light strips, control a heated build platform, and much much more!
Even more features:
-Lots of Debugging LEDs and extra I/O pins broken out for hacking
-Access to I2C and UART for hacking
-Hardware-based safety cutoff for extruders
-Extra FET for hacking
-Arduino Mega Compatible
-digitally-controlled potentiometers for setting motor currents (no more trimpots!)
