BIGTREETECH EBB36 EBB42 CAN Onboard TMC2209 Driver ADXL345 Accelerometer For Extruder Raspberry Pi Ender3 3D Printer

Description
EBB=Extruder Breakout Board
Precautions：https://github.com/bigtreetech/EBB#warning-

BIGTREETECH EBB36/EBB42 CAN is a nozzle adapter board specially designed for the 42 extruder stepper motor, which is launched by the 3D printing team Shenzhen Big Tree Technology Co., Ltd. It can communicate via USB port, or CAN BUS, greatly simplifying wirings.

Suggestion:Do not turn on HDMI, it may report an error

BTT EBB36/EEB42 CAN only supports Klipper at the present.

Features
1. With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
2. Added protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heating rod.
3. 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.
4. Connect the USB witha jumper cap to get it power 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. Supports communication via CAN or USB. The terminal resistor 120R of CAN can be selected throughthe jumper cap, and it reserves CAN expansion interfaces.
9. 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.
10. The adaptor board is equipped with terminals, female reeds, double-way studs and screws, which are required accessories for DIY, greatly meeting the DIY needs of customers.
11. NO MAX31865.
