3d Printer Mega Ultimaker Shield Compatible with RAMPS

MEGA Ultimaker Shield;

This product is an Arduino Mega shield, made for Ultimaker's UltiStepper Driver, compatible with Pololu stepper driver boards. This is a board that's very similar to other Pololu-based electronics implementations, including RAMPS, but it can support up to 5 steppers (three for X, Y, Z, one for an extruder and one for any other function). You can add as many stepper driver carriers as you need. It is designed to run at higher voltages than 12 Volts, this allows you to put 90 Watts out of one MOSFET and run your stepper motors with more torque and higher maximum speeds. It has a a header for adding an SD card module, an IDC header for adding an LCD panel (movie here), a PWM output with power for LED arrays and other lighting and a serial I/O header for Bluetooth and Ethernet add-ons.

Note: the jumper (closer the VR-tube 7812TVis connected ,the power of Arduino MEGA Ultimaker Shield also will power on the Mega.

Features:

Plug in all motors with simple 4-way JST connectors.

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.

Configurable step sizes by placing jumpers

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 thermostat inputs. The 100K thermostat is recommended.

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.

LCD backlight dimming can now be software controlled
