Megatronics is based on many famous open-source products including: Arduino Mega 2560, RAMPS and SD Ramps. Therefore 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. 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 therefore be easily programmed from the Arduino IDE.

  • Operating Voltage Electronics:5V
  • Operating Voltage High:12-24V (15A heated bed, 7A electronics)
  • DC Current per I/O Pin:40mA
  • Clock Speed:16Mhz


  • Two thermocouple inputs
  • Three Thermistor Inputs
  • On Board Micro SD card socket
  • Support for 6 stepper drivers
  • SMD fuses and MOSFETs
  • Extra MOSFET, making 4 regular MOSFETs and one for heated bed.
  • Support for the new DRV8825 Pololu stepper drivers
  • The board can be powered from 12V1 (12V MAX), by setting a jumper
  • The LCD contrast can be adjusted with a trimpot
  • 12V1 has a diode to protect against reverse polarization
  • 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.
  • Four layer high quality PCB board
  • Approximately 91 x 110mm
