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
