BIGTREETECH SKR Pro v1.2 32bitHighPerformance 3D Printer Control Board
SKR Pro v1.2 Features1) The main control uses the ARM-level Cortex-M4 series with a32-bit dominant frequency of 168 MHz STM32F407ZGT6 chip,performance is greatly improved;2) Equipped with highly modular open source firmware Marlin2.0, itis convenient for users to DIY and further-development, to avoidthe 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 followingadvantages: it supports online debugging, which is more helpful forproduct development and performance optimization, and uses Clanguage for development, which is easy to get started.4)The PCB board layout is rigorous and beautiful, and it is speciallydesigned 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 bereduced to 1/4, effectively solving the heating problem of hot bedMOS tube.7) BIGTREETECH-2.8-inchTFT, and BIGTREETECH-3.5-inchTFTcolor touch screens are compatible, as are LCD2004 andLCD12864 screens.8) The system supports Chinese simplified Chinese, English andother 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 iscut off, materials can be discovered when broken, and works canbe 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, I2Cand SPI.16) Use the power supply option to separate the USB power supplyfrom the switching power supply, which can effectively prevent thecomputer USB port from being burnt due to a short circuit.17) The special function interface uses a color-conspicuous rowpin to greatly reduce the error rate of the wiring.18) As many as 20 expansion ports can be reserved, andextended ports can be used to add more features to theprinter without worrying about the shortage of motherboardports.19)Support offline printing and online printing.20) Support for dual Z axis printers (series dual Z)
