Megatronics is based on many famous open-source products including: Arduino Mega, RAMPS, SD Ramps. Therefor this product is an already proven design. It combines all major features of these board into a single board solution for more reliable 3D-printing. This board will get you the most features for the best price!
Megatronics has a powerful Atmega2560 processor with 256 kB memory, running at 16Mhz. The board can be connected to a PC using a normal USB cable. It will register as FTDI FT232R device. The board is compatible with the Arduino Mega 2560 and will therefor be easily programmed from the Arduino IDE.
This is only the board. Stepper drivers are not included.

Thermo couple (4x)
On board support for connecting 4 thermo couples
Autonomous printing from Micro SD card on board, also an external SD card is supported
Hooking up a LCD is pretty easy. The Wiring is compatible with most LCD screens. We do not sell the required wiring yet, but you can use 6×2-wire cable.
The board has 3 MOSFETs (3x 25A) to support extruders, 2 MOSFETs fior fans and 1 MOSFET (IRLS3034PBF) for the heated bed
Four thermistors are supported.
Up to 6 stepper drivers
Compatible with RAMPS, 6 slots for stepper drivers (not included). Modularized to make replacement easy for damaged drivers. This board also support the new DRV8825 driver
Support for many peripherals
The board’s functions can be easily extended with LCD, keypad etc. See the connectors section for more information
USB 2.0 Full Speed compatible
Auto reset can be disabled by removing a jumper
The board can be powered from 12V1 (12V MAX), by setting a jumper
The LCD contrast can be adjusted with a trimpot
The 5V line is protected by a 500mA resettable fuse
A piezo is included to allow the printer to give feedback with sound
Each stepper driver slot has a breakout to connect external stepper drivers to the board.
