This is the upgraded version of the BIGTREETECH SKR V1.3 Control Board
We have already issued a merger request for SKR PRO V1.1 to Marlin. The merger request needs to be approved by Marlin's official website. It takes a while.
At present, the firmware disclosed on GitHub website is actually the marlin2.0 firmware. You can use the firmware that we have disclosed before the merger. After the merger is completed, you can download the firmware from the official website of Marlin.
TMC2130 SPI/TMC5160 SPI ,only with 5pcs cable, SKR PRO has onboard SPI function,so TMC2130 SPI /TMC5160 don't need to use cable on SKR PRO.
