  • Description
Using This suite (1pcs RAMPS 1.4 Controller Board+ 5pcs A4988 Stepstick Stepper Motor Driver Module with Heat Sink on your Arduino-compatible MEGA shield for easy service,part replacement,upgrade-ability and expansion.

Key Features:
RAMPS 1.4 Controller
● Expandable to control other accessories.
● 3 Mosfets for heater / fan outputs and 3 thermistor circuits.
● Fused at 5A for additional safety and component protection
● Heated bed control with additional 11A fuse.
● Fits 5 Pololu stepper driver boards.
● Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.
● I2C and SPI pins left available for future expansion.
● All the Mosfets are hooked into PWM pins for versatility.
● Servo style connectors are used to connect to the end stops, motors, and LEDs. These connectors are rated for 3A, very compact, and globally available.
● SD Card add on available.
● LEDs indicate when heater outputs on.
● Option to connect 2 motors to Z for Prusa Mendel.

● Simple step and direction control interface.
● Can interface directly with 3.3 V and 5 V systems.
● Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout.
● Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.
● Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates.
● Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
● 45 V maximum supply voltage.
● Built-in regulator.(no external logic voltage supply needed)

Packing List:
● 1 x RAMPS 1.4 controller board
● 5 x A4988 Stepstick Driver
