BIGTREETECH EBB36 EBB42 CAN Onboard TMC2209- v1.2

BIGTREETECH EBB36 EBB42 CAN Onboard TMC2209- v1.2 Description

Features:
brand new and high quality
With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
Added for 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 for protection on the power interface prevents users from burning the motherboard when mistakenly connecting the reverse power line during DIY.
