BIGTREETECH EBB 36 V1.2(G0B1) CAN-BUS BOARD WITH MAX31865

The BIGTREETECH EBB36, toolhead adapter board is made to fit onto 36mm round stepper motor extruders, developed by the 3D printing team at Shenzhen Big Tree Technology Co., Ltd.
This innovative module is designed to facilitate seamless communication through both USB and CAN, offering a simplified wiring experience for 3D printer toolheads.
With its advanced capabilities, the EBB36 streamlines operations and enhances overall printing efficiency, making it an indispensable component for your 3D printing setup.

Main Features:

• With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.

• The added protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heater cartridge.

• Users can select the thermistor's pull-up resistor values through a jumper wire, so as to support PT1000 (2.2K pull-up resistors), which makes it convenient for DIY.

• Connect the USB with a jumper cap to get it powered 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 adaptor board is equipped with terminals, female reeds, double-way studs and screws, which are required for DIY, greatly meeting the DIY needs of customers.
