Product Profile
BIGTREETECH MMB CAN V1.0 is a control board for multi-material 3D printing
system, e.g., ERCF. It simplifies wiring by communicating via USB or CAN.
Feature Highlights
 The board has BOOT and RESET buttons, allowing users to update
firmware in DFU mode via USB.
 I2C interface reserved for filament run out/clogging detection, or other DIY
functions.
 The power interface has reverse polarity protection to prevent the board
from being damaged if power cables are connected incorrectly during DIY.
 Supports CAN or USB communication, with selectable 120R terminal
resistance for CAN and reserved CAN expansion interface.
 USB port has ESD protection to prevent controller damage from
electrostatic discharge.
 Uses XT30 interface for CAN communication and board power supply,
simplifying wiring.
 Stepper motor driver supports high and low voltage selection for DIY use.
