BigTreetech SKR Pro V1.1 Board WIFI and TFT35 Touch Screen Kits +6PCS TMC2209
SKR Pro V1.1 Control Board:
This is the upgraded version of the BIGTREETECH SKR V1.3 Control Board
TMC2130 SPI – only with 5pcs cable, SKR PRO has onboard SPI function,so TMC2130 SPI don’t need to use cable on SKR PRO.
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.
