BIGTREETECH EBB36 CAN Bus Adapter Board with MAX31865 Hot End PCB Board Filament Break Blockage Detection for 36 Stepper Motor Extruder Nozzle Head Tool for Blv Ender 3 - đź’–Smart Upgrade: Onboard MAX31865, support 2-wire/4-wire PT100/PT1000 selection, support CAN or USB communication, among which CAN terminal resistance 120R can be selected by jumper cap, and reserved CAN expansion interface, reserved RGB interface , to meet the lighting needs
- đź’–Easy to Use: It is a 36-step (42-step) motor extruder nozzle adapter board, which can communicate through USB or CAN, which greatly simplifies wiring. BOOT and RESET buttons are reserved on the motherboard, users can enter DFU mode through USB to update the firmware
- đź’–Superior Security: The EBB series has been optimized in multiple dimensions in terms of security. USB power-on is selected by jumper cap, which effectively isolates the DC-DC and USB 5V of the main board, and increases the protection circuit of the thermistor part to avoid the burning of the main control chip due to the leakage of the heating rod. The USB port adds an ESD protection chip to prevent the main control from being damaged. Electrostatic breakdown of the USB port.
- đź’–Rich Expansion Functions: I2C interface is reserved. This port can also be used for material breakage, material blocking detection, or DIY operations for other functions. The factory is equipped with terminals, female reeds, double-way studs and screws for Meet the DIY needs of customers
- đź’–Quality Commitment: Q: When updating firmware, it may be a risk that the heater sticks keep heating up A: please pay attention to disconnect the main power VIN of the hotend when using the DFU of Type-C port to update the firmware, or ensure that the firmware update is completed soon and goto the normal working mode. Never keep MCU in DFU mode for a long time when the main power supply and hotend are connected.If you still have any questions, Please feel free to contact us
Product parameters1. Appearance size: 51.5mm*37mm2. Installation size: hole spacing 43.85mm, M3 screw hole*23. Microprocessor: ARM Cortex-M0 STM32G0B1CBT64. Input voltage: DC12V-DC24V 6A5. Logic voltage: DC 3.3V6. Heating interface: heating rod (E0), maximum output current: 5A7. Onboard sensor: ADXL3458. Fan interface: two CNC fans (FAN0, FAN1)9. Maximum output current of fan interface: 1A, peak value 1.5A10. Expansion interface: EndStop, I2C, Probe, RGB, PT100/PT1000, USB interface, CAN interface11. Motor drive: onboard TMC220912. Drive working mode: UART13. Stepper motor interface: EM14. Temperature sensor interface: 1 channel 100K NTC or PT1000 (TH0), 1 channel PT100/PT1000 optional15. USB communication interface: USB-Type-C16.DC 5V output maximum current: 1APrecautions1. When the PT1000 is not used for the TH0 interface, the jumper cap cannot be inserted on it, otherwise the 100K NTC cannot be used normally2. When using CAN communication, you need to see if it is used as a terminal. If it is a terminal, you must plug the jumper cap at the 120R position;3. When DIY crimping, you need to pay attention to the line sequence, and do DIY according to the Pin diagram to avoid the power line being reversed or connected to the CAN signal, which will cause the module to burn;4. When programming the program through the USB port, if there is no external power supply, you need to short the VUSB jumper cap to provide the module with working voltage;5. The load current of the heating rod and the fan interface should not be greater than the maximum withstand current to prevent the MOS tube from being burned out.
