3d Printer Mega Ultimaker Shield Compatible with RAMPS
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. 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 thermistor inputs. The 100K thermistor is recommended. Has a IDC header for adding an LCD panel (movie here) 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 now 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. New features and improvements of previous version: Compatible with UltiController - Mega 2560 can be self-powered from the DC-jack. - Jumper added for controlling autonomous power setting - 100 uF connection to Vcc2 - High-current track from DC jack and ON/OFF switch moved slightly - Better suiting the footprint of the rocker switch
