BTT EBB42 Gen 2 BIGTREETECH Smart Toolhead Control Board for 3D Printers

BTT EBB42 Gen 2 BIGTREETECH Smart Toolhead Control Board for 3D Printer Part

• BTT EBB42 Gen 2 are next-generation CAN bus toolhead boards developed by BIGTREETECH to simplify wiring, improve signal stability, and enhance overall 3D printer performance.
• Designed specifically for Klipper-based CAN systems, these boards mount directly on the toolhead, drastically reducing cable clutter and improving reliability.
• Both Gen 2 boards feature high-speed CAN communication, robust power management, and support for hotend heaters, fans, thermistors, extruders, probes, LEDs, and sensors.
• The compact PCB design ensures minimal added weight, making them ideal for high-speed CoreXY and lightweight toolhead setups.
• The EBB42 Gen 2 is optimized for compact toolheads and lightweight extruders, while the EBB42 Gen 2 supports larger NEMA 17 extruders with higher current requirements.
• With improved PCB layout and enhanced component quality over Gen 1, these boards deliver better thermal performance, stable signal transmission, and long-term durability.
