Casekingdom LCD12864 RAMPS 1.4 Board 2560 R3 Control Board A4988 Driver Kit For 3D Printer

  • A4988 driver:
  • Low RDS (ON) outputs
  • Automatic current decay mode detection / selection
  • Mixed with slow current decay mode
  • Synchronous rectification for low power dissipation
  • Internal UVLO
  • Crossover current protection
  • 3.3 and 5V compatible logic supply
  • Thermal shutdown circuit
  • Ground short circuit protection
  • Load short-circuit protection
  • Five selectable stepper modes: full, 1/2, 1/4, 1/8 and 1/16
  • Product Features

    • Power design of Mega 2560 R3 board. Arduino Mega power supply system has two options, USB direct power supply or an external power supply. Select the power supply will automatically switch.
    • Optional external power supply AC-to-DC adapter or battery, this limits the control board voltage range 6V ~ 12V. but if the voltage supplied is less than 6V, I / O ports may not provide the 5V voltage, so there will be no stable;
    • if the supplied voltage is greater than 12V, the regulator will have the device may overheat protection. are more likely to damage the Arduino MEGA. Therefore, the operation of the proposed power supply 6.5 ~ 12V, 7.5V or recommended power supply is 9V.
    • CD12864 Feature. Large screen: 12864LCD
    • Integration SD card in the back, after slicing the file into the SD card, you can select the corresponding files on the LCD. The board has encoder, can be achieved parameter adjustment, and the file selection print!

    XIDAJE HOT 3D Printer RAMPS 1.4 REPRAP A4988 Stepper Motor Drives Motion Control

    1. The RAMPS 1.4 board is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
    2. Mega 2560 board For Arduino Mega is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery. Arduino development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.
    3. A4988 driver is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.
