Eachine 3d Printer Megatronics V2.0 Reprap Stepper Motors Driver Motherboard

3D Printer Megatronics V2.0 Reprap Stepper Motors Driver Motherboard Description: Megatronics is based on many famous open-source products including: Arduino Mega 2560, 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. 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. Specification: Microcontroller: Atmega2560-16AU Operating voltage electronics: 5V Operating voltage high: 12-24V (15A heated bed, 7A electronics) DC current per I/O Pin: 40mA Dimensions: 15 x 10 x 4cm Package weight: 0.125kg Features: 1. Improved thermo couple support. 2. Second thermo couple supported 3. Support for 6 stepper drivers 4. SMD fuses and MOSFETs 5. Extra MOSFET, making 4 regular MOSFETs and one for heated bed. 6. Support for the new DRV8825 Pololu stepper drivers 7. The board can be powered from 12V1 (12V MAX) by setting a jumper 8. The LCD contrast can be adjusted with a trimpot 9. 12V1 has a diode to protect against reverse polarization 10. The 5V line is protected by a 500mA resettable fuse 11. A piezo is included to allow the printer to give feedback with sound 12. Each stepper driver slot has a breakout to connect external stepper drivers to the board. 13. Four layer high quality PCB board Package included: 1 x Steppermotors megatronics
