The SKR PRO uses the ARM-level Cortex-M4 series with a 32-bit dominant frequency of 168 MHz STM32F407ZGT6 chip, performance is greatly improved.
Equipped with highly modular open source firmware Marlin2.0,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.
Reserve extended ports of BL Touch, PWM, ADC, UART, I2C and SPI.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.
The board have 6 motor drives, 3 extruders, 3 CNC fans.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.
Support TMC5160/2130(SPI,Dir,Step)/2208(UART,Dir,Step)/2209;ST820,LV8729, DRV8825,A4988, etc.and TFT28/35, LCD2004?LCD12864.
