SB COMBO V2 StealthBurner CAN & USB

FYSETC SB CAN Tool Board V2

FYSETC SB CAN Tool Board V2 is a high-end board specifically designed for the StealthBurner printhead, offering enhanced communication and control capabilities for 3D printers. With support for Klipper firmware and two communication interfaces (CANBUS and USB), this board provides flexibility and ease of integration into various systems. The main advantage is the significant simplification of cabling – instead of a large bundle of wires leading to each component, only 4 wires (in one bundle) are needed for both communication and power. The board is equipped with several USB ports, allowing the connection of additional devices such as automatic leveling sensors or AI cameras.

This board also adds an integrated ADXL345 accelerometer to the system, enabling vibration measurement and facilitating printhead calibration and print quality optimization. The robust design with a 6-layer PCB and the use of high-quality components, such as tantalum capacitors, ensures long life and stable operation even under demanding conditions.

Key Features:

• STM32F072 Microcontroller: Klipper firmware support ensures high compatibility with modern 3D printers.
• CANBUS and USB interface: Allows flexible connection to various peripherals and control systems.
• Integrated ADXL345 accelerometer: Enables advanced vibration measurement features for print optimization.
• Simplified cabling: One cable for both power and communication instead of complex bundles of wires to each component.
• USB HUB: Three USB ports for connecting additional devices such as sensors or cameras.
• High-performance MOSFETs: Independent control of fans and heating elements with lower heat production.
