BIGTREETECH EBB SB2209 CAN V1.0 Extruder Breakout Board for Voron Stealthburner UART Mode Support Klipper with 100K NTC B3950 + 30-Pin Ribbon Wire Kit

The BIGTREETECH EBB SB2209 CAN RP2040 Extruder Breakout Board has garnered a generally positive reception from users who have integrated it into their Voron 2.4 builds. Once installed correctly, this board significantly streamlines the wiring process, converting a potential tangle of 20 wires down to just 4. Users commend the board's performance in UART mode alongside Klipper and CANBus, noting that it functions well when the setup is followed precisely. Installation can be a meticulous process, requiring careful attention to the fan board placement to prevent shorts against other components. Customers emphasize the importance of isolating potential contact points and ensuring the soldered leads are trimmed appropriately. Guides and documentation are available, but some users find discrepancies in visuals, particularly regarding settings like the Pt1000 Dip switch orientation, which can create confusion for the uninitiated. Despite some difficulties in the initial setup, users report the board operates reliably once everything is configured correctly. However, the small connectors on the PCB have drawn criticism; they are often seen as potential failure points. Some users have opted to solder wires directly into these connectors for added reliability. A notable point shared by several customers is the lack of active cooling instructions for enclosed printer setups, which they believe would be beneficial. Overall, the BIGTREETECH EBB SB2209 offers a robust solution for those looking to reduce cable clutter and enhance their 3D printing experience, provided they are willing to invest the time in proper installation and configuration. **
