The BIGTREETECH EBB SB2209 / SB2240 USB is an excellent solution for the Voron StealthBurner, especially if you value a clean, minimal, and reliable installation.
One of the biggest advantages of this board is the significant reduction in cabling. By placing the electronics directly on the toolhead, the wiring harness becomes much simpler, cleaner, and easier to manage. This greatly improves both aesthetics and serviceability of the printer.
Using USB instead of CAN makes the installation and configuration straightforward and hassle-free. There is no need for additional CAN adapters, terminators, or complex firmware setups. The board works reliably with Klipper and is detected immediately, which makes setup fast even for users who want to avoid unnecessary complexity.
The SB2209/SB2240 integrates perfectly with the StealthBurner ecosystem, offering a compact form factor, good connector layout, and stable operation. It feels like a well-thought-out, practical solution rather than an experimental add-on.
Overall, this is a very solid and user-friendly upgrade for Voron StealthBurner builds, combining simplicity, reliability, and a much cleaner wiring solution. Highly recommended for anyone who prefers a tidy toolhead and an easy setup process.
