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.
Improved thermo couple support.
Second thermo couple supported.
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.
