1. External Dimensions: 40mm x 40mm.
2. Installation Dimensions: Hole spacing 31mm x 31mm, M3 screw hole x 4
3. Microprocessor: ARM Cortex-M0 STM32F072C8T6 48MHz
4. Input Voltage: DC12V-DC24V 9A
5. Logic Voltage: DC 3.3V
6. Heating Interface: Heating Rod (E0), maximum output current: 5A
7. Onboard Sensor: ADXL345
8. Fan Interfaces: Two CNC Fans (FAN0, FAN1)
9. Maximum Output Current of Fan Interface: 1A, peak value 1.5A
10. Expansion Interfaces: EndStop, I2C, Probe, RGB, PT100/PT1000, USB Interface, CAN Interface
11. Motor Drive: Onboard TMC2209
12. Driver Working Mode: UART
13. Stepper Motor Interface: EM
14. Temperature Sensor Interface(Optional): 1 channel 100K NTC or PT1000 (TH0), 1 channel PT100/PT1000
15. USB Communication Interface: USB-Type-C
16. DCDC 5V Maximum Output Current: 1A
Cautions
1. When the TH0 interface doesn’t use PT1000, you can’t insert the jump cap on it, otherwise 100K NTC won’t be used as normal.
2. When using CAN communication, you need to see whether it is used as a terminal. If it is, you must insert the jumper cap on the 120R position.
3. When DIY crimping, you need to pay attention to the line sequences, and do DIY according to the Pin diagram so as to avoid the power line from being reversely connected or connected to the CAN signal, which will get the module burned.
4. If there’s no external power supply during writing firmware via USB port, you need to short the VUSB by jumper cap so as to supply the module with working voltage.
5.The load current of the heating rod and the fan interfaces shall not exceed the maximum withstand current to prevent the MOS tube from being burned out.
FAQ

【CAN Bus Communication】BTT EBB42 CANBus extruder breakout board V1.2 supports communication via CAN or USB. CAN Bus communication features stabler data transmission in longer distances with shorter delay. The terminal resistor 120R of CAN can be selected through jumper cap. EBB42 CANBus also has CAN expansion interfaces.
【Simplify Wiring】BIGTREETECH EBB42 CAN BUS exrtruder toolboard helps to clean up your tool head’s wiring by having all wires go to the board instead of running them all the way down to your main control board. Get rid of the messy wires and enjoy a neat and convenient wiring!
【Rich Expansion Interfaces】Reserved I2C interface allows filament broke/clogged detection, and supports other DIY functions. Onboard MAX31865 supports selecting 2-wire or 4-wire of PT100/ PT1000. With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
【Enhanced Safety】Added protection circuit on the thermistor can avoid leakage from the heating rod burning the main control chip. Equipped ESD protection chip on the USB port prevents the motherboard from being broken down by the static electricity of the USB port. Anti-flyback diodes on the heating rod and fans’ ports effectively protects the MOS tube from being burned due to reverse voltage. Anti-reverse connection design on the power interface prevents motherboard from burning in reverse co
【DIY Friendly】User can select the thermistor’s pull-up resistors values through jumper wire, so as to support PT1000 (2.2K pull-up resistors), making it convenient for DIY. BIGTREETECH EBB42 CAN BUS 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.
