Combined with a4988 driver and atmega 2560, it's convenient for dismantling and debugging, performance is too much better than melzi. Unlike melzi integration motherboard, once some parts damaged, disassembling maintenance is troublesome.
Stable and reliable, fair price and thickened circuit board.
With rules of cartesian coordinate robot and extruder.
Can control spare parts.
With heater/fan output/three thermistor MOSFET.
Integrated 5A extra safety and components protection.
Suit for 5 Pololu stepper driver plate.
Pololu plate pin socket.
I2C/SPI pin for future development.
All MOSFET with PWM pins are universal.
Servo connector used to connect lift stop, motor and lighting diode. Rated current 3A.
SD card add Kliment – Sdramps.
When LED indicates heater output, two motors connect to Z Prusa Mendal.
Used as a 3D printer, need to form a complete set of circuit module:
2560 CPU core board for Arduino, RAMPS 1.4 panel main control board, A4988 driver board, stepper motor driver module (single head 4pcs, double head 5pcs), LCD controller LCD control, SD card offline printing (optional matching)
