This board is for Arduino MEGA as Ultimaker UltiStepper drive and compatible with Pololu stepper driver boards.
You can add as many stepper driver carriers as you need.
It is very similar to other Pololu based electronic implementation, including RAMPS, but it can support up to five steppers (three for X, Y, Z, one for an extruder and one for any other function.)
It is designed to run at a higher voltage than 12 volts, which allows you to put 90 Watts out of one MOSFET and run your stepper motors with more torque and higher maximum speeds.
Plug in all motors with simple 4-way JST connectors.
Made for Ultimaker's UltiStepper Driver.
Compatible with Pololu stepper driver boards.
Configurable step sizes by placing jumpers.
3 x 55 Amp MOSFETs outputs (with LED indicators. Actual current capability limited by PCB and connectors).
All pins are broken out for maximum extensibility.
Runs from 15V to 19V.
Three thermocouple inputs, or thermistor inputs. (The 100K thermistor is recommended).
Has a IDC header for adding an LCD panel.
Has a header for adding an SD card module.
A toggle - switch for powering up / down the board.
Easier to wire up thermocouples.
Includes a 12V regulator for an (always on) fan to cool the electronics.
A PWM output with power for LED arrays and other lighting.
LCD backlight dimming can be software controlled.
A serial I/O header for bluetooth and ethernet add-ons.
Servo outputs for experimental setups.
They need to be interrupt or software driven as the pins routed to the servo header I/O do not have PWM.
When the jumper (closer the VR-tube 7812TV) is connected, the power of Arduino MEGA Ultimaker Shield also will power up the Mega.
