Ramps 1.4 Controller Board
This list is Pololu trillion rupiah or ramps short. It was designed as a low-cost small package
RepRap needs to accommodate the entire electronics . Oblique interfaces with the powerful
Arduino MEGA platform Arduino Mega and have plenty of room for expansion. On the stepper
drives and a Arduino MEGA shield extruder control electronics for easy maintenance replacement
parts upgrades and expansion capabilities including plug-in modular design . In addition some
Arduino expansion boards can be added to the system as long as the main ramp plate is saved
to the top of the stack .
The board is mainly based on Adrian 's Pololu_Electronics and work Tonok 's . The proposed anti- Vick
copper etching method . Vick is also inspired by the work of EasyDrivers . Adrian'sPololu_Electronics
circuit design mainly based on Joaz RepRapSource.com provide initial pin definitions and many design
improvements. Too much inspiration advice and from Prusajr Kliment Maxbots Rick and many other
ideas RepRap community.
It has Cartesian robots and regulations of the extruder .
Extended to control other accessories.
Heater / MOSFET outputs and three fan thermistor circuit.
Integration of additional security 5A and component protection
Control of additional heating bed 11A fuse
Suitable for 5 Pololu stepper driver board
Pololu board pin socket so they can be easily replaced or removed for future designs .
I2C and SPI pins left for future expansion.
Hooked into all MOSFET PWM pin versatility.
Servo type connector is used to connect to the end stop the motor and the light-emitting diodes.
These connectors are gold-plated rated current of 3A very compact.
On the SD card to add - is now available from the Kliment - Sdramps
LED indicate when the heater output
Option 2 motors connected to Z Prusa Mendel

12864 LCD Controller Board
3D printers use LCD control panel are ramps extension accessories. LCD control panel through
which you can achieve spooling is the 3D model Gcode files are copied to the SD card and then
print the file via the LCD control panel. This version is an upgraded version of reprap smart controller.
DRV8825 Stepper Motor Driver
The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is
a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier
is almost the same so it can be used as a better performance of the pull-down menu board
replacement in many applications. DRV8825 features an adjustable current limit overcurrent and
overtemperature protection six micro-resolution (down 1/32-step). It uses 8.2 - 45 V can provide
up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient
additional cooling).
A simple steps and direction control interface
Six different steps resolutions: full step half step 1/4-step1/8-step1/16-step 1/32-step
CAN interface directly with 3.3 V and 5 V systems
Over-temperature thermal shutdown overcurrent shutdown undervoltage lockout
Short to ground short circuit load protection
4 Layer 2 oz copper PCB in order to improve heat dissipation
Exposed solder ground below the bottom of the driver IC on the printed circuit board pad
Module size pin and interface matching A4988 stepper motor driver operators in many ways
Adjustable current control lets you set a potentiometer which lets you use the stepper motor's
rated voltage or more in order to achieve a higher rate of maximum output current step
Intelligent chopping control automatically selects the correct current decay mode (fast decay or
slow decay)
Maximum 45 V supply voltage
Built-in voltage regulator (the need for any external logic supply voltage)
Limit Switch Endstop
Quality switching elements.
Customized high quality connection using 22AWG wire copper wire inside is very thick can be
resistant to current 2A 300V voltage. An insulating layer over a wide range of temperatures up to
80 degrees. Is the common connection of thin copper wire can not match. Not easy to pull off plug
it convenient for ease of use plug the other side to do the one you can use the direct plug.
Red line connecting VCC (ramps of +)
Connect the black wire GND (ramps of -)
Green Line connection SIGNAL (ramps in s)
tips: Under normal circumstances the system must be configured to at least three mechanical switches.
Pros: Easy to install the more common styles.
Disadvantages: easy to wear and tear of mechanical parts service life is shorter
