3D Printer Accessories Arduino MEGA Shield Control Board Package weight: 0.05 kg Descroption: 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. Features: 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. Note: When the jumper (closer the VR-tube 7812TV) is connected, the power of Arduino MEGA Ultimaker Shield also will power up the Mega.

Features:  Latest V5.5 version Power supply voltage input requirements: DC 12-24V (The optimum voltage is 24V), 1.5-3A Temperature: about 200 to 480 ° C Dimensions: 1.75cm*1.06cm*0.45cm (±0.04cm)   Control board indicator:   Without soldering iron head: After powered, it will flash red light once, then quickly flash green light and keeps lighting. With soldering iron head: After powered, it will flash red light for 6-8 seconds, then the red and green flashing alternately. Red light flashing speed is related to the temperature, the higher the temperature, the faster the red light flashes.   Package includes:    1 x DC 12-24V Mini T12 Temperature Control Board Kit(include the mini control board, potentiometer,LED and knob, not solder together)   Details pictures:

Reprap Ramps-FD Control Board Ramps1.4 Improved Version For 3D Printer Introduction: When you use Arduino Due as the controller of your 3D Printer, you may find the RAMPS1.4 is not compatible with DUE. As you know the Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3, the importance is the Atmel SAM3X8E chip used on the Due operates at 3.3V,worse applying 5V to the Due's inputs will likely damage the chip. So we create a new RAMPS variant which is compatible with the Due to replace Ramps1.4. Why choose Ramps-FD instead of Ramps1.4? The RAMPS-FD has other hardware protection, through the jumper cap control motor drive IC The RAMPS-FD much more than Ramps1.4 2-way PWM The RAMPS-FD has larger driving power than Ramps1.4 The RAMPS-FD power has two choices: 12V and 24V Why choose Arduino DUE instead of Arduino MEGA? CPU operates at 3.3V High-current IO pins are capable of 15 mA source, 9 mA sink Low-current IO pins capable of 3 mA source, 6 mA sink CPU package has an absolute max of 130mA The Due has 1 dedicated SPI port, and 4 multipurpose USART/SPI ports. The SPI port is only routed to the 6 pin header used for ICSP on Mega, but this is not used for ICSP on Due The Due does not have any EEPROM Due has lower power, computing faster and flash, sram bigger than mega2560 Package included: 1 x Ramps-FD Control Board
