Bigtreetech EBB SB2209 CAN

The BIGTREETECH EBB SB2209 CAN is a high-performance toolboard designed for Voron StealthBurner and Klipper-based 3D printers. Featuring an onboard TMC2209 stepper driver and ADXL345 accelerometer, it enables precise motion control and resonance compensation, making your 3D printing experience faster, smoother, and more reliable.

Built around the STM32G0B1CBT6 32-bit MCU (64MHz), this module ensures stable communication via CAN bus or USB. With simplified wiring and robust anti-interference capability, CAN technology improves stability and efficiency, while USB mode provides straightforward plug-and-play connectivity.

The EBB SB2209 supports heaters, sensors, and fans directly, including PT100/PT1000, 100K NTC thermistors, and multiple fan outputs with independent voltage selection. Thanks to its drop-in design for the Voron StealthBurner, installation is clean and hassle-free, with no soldering required.
