BigTreeTech U2C V2.1 and EBB36 CAN V1.2 (G0B1) Klipper expansion device for 3D printer

✨ EBB36 CAN V1.2 (G0B1)
Nozzle adapter board designed for 36 stepper motor extruder
Main 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.
> 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.

✨ U2C V2.1.
USB to CAN bus module used to convert the USB port of the raspberry pi to connect with a 3D printer motherboard and other products through CAN bus. CAN bus has many advantages in the field of industrial control such as a long transmission distance and large number of nodes that can be mounted on it at the same time.
Main Features:
> Support CAN bus connection, long data transmission, strong anti-noise ability strong real-time performance, and high reliability.
> The surface of the PCB adopts the ENIG process.
> The TYPE-C port is equipped with ESD protection to prevent static electricity from damaging the hardware.
> Support firmware updates for the motherboard through SWD or hardware DFU.
> More than on the CAN interface.
