The SKR PRO uses the Cortex-M4 series at the ARM level with a 32-bit dominant frequency of 168 MHz. The STM32F407ZGT6 chip significantly improves performance.
Visual Studio Code is a powerful development tool for Marlin2.0. The integrated development environment provides the following benefits: it supports online debugging that is more useful for product development and performance optimization, and uses the C language for development that is easy to get started.
Reserve extended ports for BL Touch, PWM, ADC, UART, I2C, and SPI. Use the power supply option to disconnect the USB power supply from the switching power supply. This can effectively prevent the computer’s USB port from being burned by a short circuit .
The board has 6 motor drives, 3 extruders and 3 CNC fans. Up to 20 expansion ports can be reserved and extended ports can be used to add more features to the printer without worrying about the lack of motherboard ports.
Supports TMC5160 / 2130 (SPI, Dir, Step) / 2208 (UART, Dir, Step) / 2209, ST820, LV8729, DRV8825, A4988 etc and TFT28/35, LCD2004 4 LCD12864.
