Bigtreetech MMB CAN ERCF Control Board

Bigtreetech MMB CAN ERCF Control BoardThe Bigtreetech MMB CAN is a control board for multi-material 3D printing systems, e.g. the ERCF. It simplifies wiring by communicating via USB or CAN.Feature HighlightsThe board has BOOT and RESET buttons, allowing users to updatefirmware in DFU mode via USB.I2C interface (2x on the V2.0 board) reserved for filament run out/clogging detection, or other DIYfunctions.The power interface has reverse polarity protection to prevent the boardfrom being damaged if power cables are connected incorrectly during DIY.Supports CAN or USB communication, with selectable 120R terminalresistance for CAN and reserved CAN expansion interface.USB port has ESD protection to prevent controller damage fromelectrostatic 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.Why MMB CAN?32-bit, 64 MHz2 2 EZ Driver Sockets (requires EZ driver modules!)1 10 Endstop PortsCAN busHigh-Voltage Driver Sockets (up to 60V)High Performance You Can Rely OnHarness the power of the 32-bit, 64 MHz ARM Cortex-M0 series MCU, the STM32G0B1CBT6, for precise control, ensuring exceptional print quality and reliability in your ERCF project.Redundancy Meets FlexibilityThe redundant design of the drivers and endstops provides backup interfaces and supports the DIY AMS project, increasing reliability and flexibility.Simplified Wiring with CANEnjoy reliable communication, simplified wiring, and robust, stable data transmission for a smooth and efficient printing experience.*The CAN bus interface is only functional when running the Klipper firmware.More PossibilitiesI2C Interface: Easily connect BME680/BME280 temperature and humidity sensors to obtain real-time environmental readings.Infrared Sensor Interface: Easily connect the TCRT5000 infrared sensor for precise detection and automated calibration capabilities.RGB Interface: Allows easy addition of NeoPixel/WS2812 LED strip.SpecificationsDimensions 125mm x 54mm (V2.0: 108mm x 59mm)Microprocessor ARM Cortex-M0 STM32G0B1CBT6 64MHzInput Voltage DC12V-DC24V 9ALogic Voltage DC 3.3VServo Interface (MOT)Maximum Output 5V 2A, peak 2.5AExpansion InterfacesSTP1-STP11, I2C (V2.0: 2x I2C), RGB, Sensor (infrared sensor interface), USB, CANMotor Driver Support EZ Drive (supports voltage selection)Driver Operating Modes STEP/DIR, UART, SPIStepper Motor Interfaces M1, M2, M3, M4USB CommunicationInterface USB Type-CDCDC 5V OutputMaximum Current 3.6AMore info on GIT
