Features: - This product is an Arduino MEGA as Ultimaker UltiStepper drive is compatible with Pololu stepper driver boards of a board. This is very similar to other electronic-based realization of Pololu including RAMPS it can support up to five stepper motors (three as X one of the other functions Y Z an extruder). You can add as much as you need stepper drive carriers. It is designed to run at a higher voltage than 12 volts which allows you to put a 90-watt MOSFET and run your stepper motor with more torque and higher top speed. It has a head increasing the SD card module IDC head added LCD panel ( movie ) PWM output power LED arrays and other lighting and serial I / O Bluetooth and Ethernet add-ons . Note : Connect Jumper ( nearly VR tube 7812TV) Arduino MEGA Ultimaker control panel will also have the power. - Simple 4-way JST connector plug for all motors . - Stepper motor control up to 5 ( 3 X Y and Z axes extruder ( in "E axis" ) you can optionally add another axis by adding a Pololu stepper drives . - By jumper configuration steps. - 3 times 55 amps output MOSFET (with LED indicator. Actual current limited capacity PCB and connector) - All leads are breaking the maximum scalability from 15V to 19V. - Thermocouple input or thermistor input. 100K thermistor recommendations. - Power on / switch documented board. - Thermocouple wiring easier . - (Normally open) fan-cooled electronic device includes a 12V regulator.
