FYSETC SB COMBO V2 CAN & USB ToolHead Controller for VORON StealthBurner

SB COMBO V2 is a newly designed SB tool board running Klipper firmware, based on STM32F072. It supports two communication modes: CAN bus and USB. An onboard USB hub provides up to three USB interfaces, allowing connections to devices such as the IDM Scanner Leveling Sensor, camera, and more. The included auxiliary board can also be attached for expanded functionality.
