Bộ Điều Khiển Máy In 3d Mega 2560 R 3 + Ramps 1.4 + Lcd 12864 + 6gong 4988 Driver

Ramp 1.4:。
The list is polo lu trillion rupees, or short ramp.
It is designed as a low-cost small encapsulation re repair needs, to adapt to the entire electronic product.。。
Characteristics:。
It has cartesian robots and extruder requirements.
Extend to control other attachments.
Heater/mosfet output and three fan thermal resistance circuits.
Integrate additional security 5a and component protection.
Control extra heating bed 11a fuse.
Suitable for 5 pololu step drive boards.
Polo luloupe socket, make it easy to replace or delete future designs.
The i2c and spi pins left for future extensions.
Multifunctionality connected to all mosfet pwm pins.
A servo connector is used to connect to the end stop、 motor and light emitting diodes.
These connectors are gold plated, rated current is 3a, very compact.
Add to the sd card-you can now sprint from kliment-sprint.
Indicates when the heater is output.
Option 2 is connected to the motor of z prusa mendel.
