BIGTREETECH EBB36 CAN is a nozzle adapter board specially designed for the 36 extruder stepper motor. They can communicate via USB port, or CAN BUS, greatly simplifying wirings.
Note: Please ensure you have compatible board that support CANBUS or you need U2C connected to your raspberry pi.
Note: Wiring is not included. We do recommenced using FEP/PTFE wiring if using drag chains. Kit include one set of each tool head connectors and pins, excluding type c cable. Ensure your power line(24/12v) have enough AWG (20-22AWG), while dataline 24-26awg is suitable or source a 4 core 22 awg wire. Ensure you have fuse on power line when possible.
Note: Always verify STM chip version when flashing firmware.

Features:
- With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
- Added protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heating rod.
- User can select the thermistor's pull-up resistors values through jumper wire, so as to support PT1000 (2.2K pull-up resistors), which makes it convenient for DIY.
- Connect the USB witha jumper cap to get it power on, which effectively isolates the main control board DC-DC from USB 5V.
- Reserved I2C interface allows for filament broke and clogged detection, and supports other DIY functions.
- Added anti-flyback diodes on the heating rod and fans' ports effectively protect the MOS tube from being burned due to reverse voltage.
- Anti-reverse connection protection on the power interface prevents users from burning the motherboard when mistakenly connecting the reverse power line during DIY.
- Onboard MAX31865 supports selecting 2-wire or 4-wire of PT100/ PT1000.
- Supports communication via CAN or USB. The terminal resistor 120R of CAN can be selected through the jumper cap, and it reserves CAN expansion interfaces.
- Equipped ESD protection chip on the USB port prevents the main control board from being broken down by the static electricity of the USB port.
- The adapter board is equipped with terminals, female reeds, double-way studs and screws, which are required accessories for DIY, greatly meeting the DIY needs of customers.
