Ramps kit

RAMPS 1.4 + Mega2560 R3+ A4988 Optical Endstop 3D Printer Kit Feature: RAMPS 1.4: It is a Mega Pololu Shield, or RAMPS for short, designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Mega with the powerful MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Mega 2560 board: Mega2560 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. This 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. A4988 driver: This product 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. Package includes: 1 x RAMPS 1.4 1 x Mega 2560 R3 4 x A4988 driver 15 x Jumper Cap 1 x USB Cable 1 x RAMPS 1.4 wiring cable

3D printer kit RAMPS 1.4 + arduino Mega + 5pc DRV8825 + 5pc heatsink + 12864 Display LCD 3D Printer Controller +Adapter For RAMPS 1.4 Reprap Mendel. Brand new, packaged in anti-static wrapping. One-day shipping (R120)

Introduction:   The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. the module pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it may be a better performance from the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, overcurrent and overheating protection, six micron resolution (down 1/32-step). the use 8.2-45 V, up to 1.5 per Arduino stage no heatsink or forced airflow (nominal to 2.2 per volume sufficient additional cooling). Features: 1. Simple steps and direction control interfaceStep 2. Six different resolutions: full step, half step, 1/4-step1 / 8-step1/ 16-step, 1/32-step 3.CAN interfaces directly with 3.3 V and 5 V systems 4.The over-temperature thermal shutdown, overcurrent shutdown,undervoltage lockout 5. Short-to-ground short circuit load protection 6.4 Layer 2 oz copper PCB, to improve the heat dissipation 7. bottom bare welding ground following a driver IC on a printed circuit board pad 8. The module size, pins and interface matching A4988 stepper motor driver carrier in many ways 9.The adjustable current control allows you to set a potentiometer, which lets you use the stepper motor's rated voltage or more,in order to achieve a higher maximum output current step rate 10. Intelligent chopping control automatically selects the correct current decay mode (fast or slow decay attenuation) 11. The maximum 45 V supply voltage 12. Built-in voltage regulator (the need for any external logic supply voltage) Pay attention to the direction when installation stepper motor drives Package included:   1 x Mega 2560 R3 1 x Ramps 1.4 1 x USB line 5 x DRV8825 module with heatsink 1 x PCB Heatbed MK2B 1 x 12864LCD control panel 1 x Adapter 2 X Cable
