The Ultimaker 1.5.7 board is an Arduino Mega shield, geared for the DIY 3D printer market and has some great features not found on the RAMPS compatible boards such as higher input voltage ability and power connectivity options.
Controls up to 5 stepper motors and Compatible with Pololu stepper driver boards 3D Printer Ultimaker
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 header add 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), MEGA Ultimaker control panel will also have the power.
Features
Arduino Mega Shield
Plug in all motors with simple 4-way JST connectors.
Made for Ultimaker’s UltiStepper Driver.
Compatible with Pololu stepper driver boards.
Controls up to 5 stepper motors (3 for the X, Y and Z axis one for an extruder (the “E axis”),
Optionally you can add another axis by adding a Pololu stepper driver.
3x 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 an IDC header for adding an LCD panel
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 now be software controlled
A serial I/O header for Bluetooth and Ethernet add-ons.
