It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced airflow. The A4988 Driver Stepper Motor Driver is a complete micro-stepping motor driver with a built-in converter, easy to operate.
The plug-in shield design includes plug-in stepper drivers and extruder control electronics sockets for easy service, part replacement, upgrade-ability, and expansion. The RAMPS 1.4 is an all-in-one design to fit the necessary components for a 3D printer into one plug-in shield for an Arduino MEGA.
It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The Arduino Mega is a microcontroller board based on the ATmega2560.
3D Printer Controller Board RAMPS 1.4 is a shield for the Arduino Mega 2560 and can control up to 5 stepper motors using driver modules with the A4988 or DRV8825 chip. 3D Printer Kit includes RAMPS 1.4 3D printer controller, Mega2560 with cable, and 5 pieces ofA4988 Driver with a heat sink.
