BIGTREETECH ERCF Control Board MMB CAN V2.0 with STM32 Chip Featured EZ Ports for 3D Printer Enraged Rabbit Carrot Feeder Solution

Take your multi-color 3D printing to the next level with the BigTreeTech MMB CAN V2.0 ERCF Control Board — the official “buddy board” co-developed by BTT and the Enraged Rabbit team specifically for the ERCF V2 (Enraged Rabbit Carrot Feeder V2) multi-material system.

This powerful control board acts as the central brain for reliable, fast, and precise filament selection and switching in multi-color/multi-material printing. Equipped with an STM32G0B1 microcontroller (ARM Cortex-M0+ @ 64MHz), it delivers excellent multitasking performance, stability, and responsiveness even during complex color changes.

Key Features:

• High-Speed CAN Communication — Ultra-fast and delay-free data transmission between the mainboard and ERCF V2 for smooth multi-color operation
• Stable & Reliable Multi-Color Control — Optimized for ERCF V2 to handle filament loading, unloading, and selection with high precision
• Rich Interfaces — Supports multiple motor drivers, endstops, servo, I2C, and more for flexible expansions
• Simplified Wiring — CAN bus reduces cable clutter compared to traditional setups
• Klipper Optimized — Full compatibility with Klipper firmware and sample configuration files for easy setup
