3D Printer DIY Kit Ramps1.4 A4988 Mega2560 MicroSD Endstop Thermistor
Feature:
This is a 3D Printer Starter Kit， developed specially for those beginners who are interested in 3D printer. You may learn about through using these basic projects.
RAMPS 1.4:
Extended to control other accessories.Fusion 5A additional safety and component protection.Extra bed heating control fuse 11A.Suitable 5 Pololu stepper driver board.Pololu board pin socket， so they can be easily replaced or removed for future designs.I2C and SPI pins left for future expansion.All MOSFET PWM pin is hooked into versatility.Servo connector is used to connect to the end block， the motor and the light emitting diodes.These connectors are gold-plated， rated current of 3A.LED indicates when the heater output.
A4988 driver:
