2. 3D Printer Controller RAMPS 1.4

The RepRap Arduino-compatible MEGA Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino-compatible Mega with the powerful Arduino-compatible MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino-compatible 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.

3. Arduino-Compatible Mega 2560 R3

Fully compatible with original Arduino MEGA 2560 R3, with this product, you are able to use all the Arduino open source platform to create or learn interactive objects, it will be a lot of fun while you are creating and learning it, so just get this and start it, we also provide reference pdf files that can help you to improve skills very quickly. after all, time matters, the sooner you can improve your programing skills, the sooner you can create amazing projects! Compared with UNO R3, this is with main Chip ATmega2560, with more I/O Pins, and additional 10 PWM output, of course, the EEPROM is also with larger space.
  
 
4.The DRV8825 stepper motor drive carrier plate TI DRV8825 micro bipolarbstepper motor drive is a breakthrough.
The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same,
so that it can be used as a more high-performance drop-down menu of these boards alternative in many applications.
DRV8825 features an adjustable current limit, overcurrent and overtemperature protection,six micro-resolution (down to 1/32-step).
It uses a 8.2 - 45 V, can provide up to about 1.5 per phase no heatsink or forced air flow (rated up to 2.2 per volume has enough 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
