Bigtreetech EBB36 Canbus V1.2 Bigtreetech U2C V2.1 klipper expansion device for 3d printer
Bigtreetech EBB36 Canbus V1.2/ Bigtreetech U2C V2.1 klipper expansion device for 3d printer.
- BIGTREETECH EBB36 CAN V1.2 and BIGTREETECH U2C V2.1. This CANBUS expansion solution is designed to improve toolhead connectivity and simplify cable management for modern 3D printers running Klipper CANBUS.
- The U2C V2.1 USB-to-CAN module acts as a USB CAN adapter, connecting your Klipper host (PC/Raspberry Pi/CB1/CB2, etc.) to the CAN network.
- The EBB36 CAN V1.2 toolhead board (for 36/42-size extruder motor toolheads) consolidates toolhead connections near the hotend/extruder to reduce wiring complexity, improve serviceability, and support stable communication over longer runs.
