BigTreeTech EBB42 USB/CAN Toolboard v1.2 (Without Max)

BigTreeTech EBB42 USB/CAN Toolboard (Without Max)

The BigTreeTech EBB42 is a USB/CAN Toolboard that simplifies the wiring by allowing communication via USB or CAN with a compatible controller board.

• 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.
• Connect the USB with a jumper cap to get it powered on, which effectively isolates the main control board DC-DC from USB 5V.
• In this version without the MAX31865, you can use both the PT100 or PT1000, 2 wire version only. To use the PT1000, you need to place a jumper on the board, please refer to the User Manual below
• 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.
• 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.
