1. SKR motherboard features:
1) The performance of the ARM-class Cortex-M3 series LPC1768 master chip with 32-bit main frequency and 100MHz is greatly improved;
2) Marlin2.0 uses powerful development tools, Visual Studio Code integrated development environment: support online debugging, more helpful for product development and performance optimization, using C language development, low development reputation;
3) The PCB board layout is rigorous and beautiful, and specializing in heat dissipation optimization;
4) Using a dedicated power chip to support 12-24V power input;
5) It can accept 24V input, and can reduce the hot bed current to 1/4 under the same power, effectively solving the heating problem of the hot bed MOS tube;
6) Support 2.8-inch, 3.5-inch color touch screen, support LCD2004 screen, LCD12864 screen;
7) The system supports Chinese simplified, English and other languages, which can be switched by itself;
8) Upgrade the firmware by SD card, the operation is simple and convenient;
9) The use of a pluggable fuse makes the replacement process easier;
10) The special function interface uses a conspicuous pin header to greatly reduce the error rate of the wiring.

1.The performance of the ARM-class Cortex-M3 series LPC1768 main control chip with 32-bit frequency and 100MHz is greatly improved;Reserve the extended port SERVOS of the PWM signal to support BL Touch;
2.Equipped with highly modular open source firmware Marlin2.0 and Smoothieware, it is convenient for users to DIY and secondary development, eliminating the worries of not being able to master the core code;
3.Onboard TMC2130 driven SPI mode of operation and TMC2208 driven UART mode,The utility model eliminates the complicated wiring process and can be used only by simply plugging and unplugging the jumper cap;
4.The high-performance MOSFET tube has better heat dissipation effect; it supports functions such as power-off continuous shooting, material cut detection, and shutdown;Use the power selection design ,to separate the USB power supply from the switching power supply, effectively avoiding short circuits,Causes the computer's USB port to be burned;
