BIGTREETECH SKR Pro v1.2 32bit High
Performance 3D Printer Control Board
SKR Pro v1.2 Features1) The main control uses the ARM-level Cortex-M4 series with a
32-bit dominant frequency of 168 MHz STM32F407ZGT6 chip,
performance is greatly improved;
2) Equipped with highly modular open source firmware Marlin2.0, it
is convenient for users to DIY and further-development, to avoid
the worry of not being able to master the core code;
3) Visual Studio Code is a powerful development tool for Marlin2.0.
Its integrated development environment has the following
advantages: it supports online debugging, which is more helpful for
product development and performance optimization, and uses C
language for development, which is easy to get started.
4)The PCB board layout is rigorous and beautiful, and it is specially
designed for heat dissipation.
5)Using a dedicated power chip, support 12-24V power input, output current 3A.
6)With 24V input and the same power, the hot bed current can be
reduced to 1/4, effectively solving the heating problem of hot bed
MOS tube.
7) BIGTREETECH-2.8-inchTFT, and BIGTREETECH-3.5-inchTFT
color touch screens are compatible, as are LCD2004 and
LCD12864 screens.
8) The system supports Chinese simplified Chinese, English and
other languages, which can be switched by itself.
9)The firmware is upgraded by SD card, which is simple,
convenient and efficient.
10) Support Serial WIFI Online Printing.
11) 6 motor drives, 3 extruders, 3 CNC fans.
12) It has the following functions: data can be saved when power is
cut off, materials can be discovered when broken, and works can
be turned off when finished.
13) High performance MOSFET tube, better heat dissipation effect.
14) Using removable fuse to make the replacement process easier.
15) Reserve extended ports of BL Touch, PWM, ADC, UART, I2C
and SPI.
16) Use the power supply option to separate the USB power supply
from the switching power supply, which can effectively prevent the computer USB port from being burnt due to a short circuit.
17) The special function interface uses a color-conspicuous row
pin to greatly reduce the error rate of the wiring.
18) As many as 20 expansion ports can be reserved, and
extended ports can be used to add more features to the
printer without worrying about the shortage of motherboard
ports.
19)Support offline printing and online printing.
20) Support for dual Z axis printers (series dual Z)
