Motor Driver EBB42 CAN V1.2 Board Support CAN Bus For Stepper Motor

Features:

1. With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
2. Added a protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heating rod.
3. 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.
4. Connect the USB with a jumper cap to get it powered on, which effectively isolates the main control board DC-DC from USB 5V.
5. Reserved I2C interface allows for filament broke and clogged detection, and supports other DIY functions.
6. Added anti-flyback diodes on the heating rod and fans’ ports effectively protect the MOS tube from being burned due to reverse voltage.
7. Anti-reverse connection protection on the power interface prevents users from burning the motherboard when mistakenly connecting the reverse power line during DIY.
8. The onboard MAX31865 supports selecting between 2-wire and 4-wire configurations for PT100/PT1000 sensors.
9. 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.
10. 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.
11.  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.
