Ramps 1.4 Controller Board

Color: Red

Size: 214mm x 214mm

Etching: 35um copper

Laminate: FR4 1.6mm

RAMPS interfaces an Arduino Mega with plenty room for expansion.

The modular design includes plug in stepper drivers and extruder control electronics on an Ard MEGA shield

for easy service, part replacement, upgrade-ability and expansion.

Additionally, a number of Ard expansion boards can be added to the system as long as the main RAMPS board

is kept to the top of the stack.

Version 1.4 uses surface mount capacitors and resistors to further cover edge issue cases.

12864 LCD

The intelligent controller includes an SD card reader, rotary encoders and a 20-character

× 4 line LCD display. You can easily connect it to your RAMPS 1.4 board using “smart

adapter” included.

 

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).

 

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.

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
