Feature:

1. The board has reserved BOOT and RESET buttons. Users can use USB to enter the DFU mode to update firmware

2. Thermistor can select pull-up resistance value through jumper, in this way to support PT1000 (2.2K pull-up resistance), convenient for customers DIY use

3. Onboard 2-way CNC fan, 1 way 4-wire fan interface

4. Proximity switch, CNC fan, 4-wire fan support VIN/12V/5V voltage selection

5. Onboard SPI output interface, this port is reserved with two independent IO ports, which can be used for material cut off, material blocking detection, or DIY operation of other functions

6. Onboard MAX31865, supporting 2-wire / 4-wire PT100/PT1000 option

7. CAN or USB communication is supported. The 120R terminal resistance of CAN CAN be selected through the jumper cap, and CAN ports are reserved for expansion

8. Equipped with DIY terminals, female reeds, double-way studs and screws, which greatly meet customers' DIY needs

SB2240 features

1. BOOT and RESET keys are reserved on the main board. Users can enter DFU mode through USB to update firmware.

2. The protection circuit of the on-board thermistor to prevent the main control chip from burning due to the leakage of the heating rod.

3. The thermistor can select the pull-up resistance value through the jumper, which supports PT1000 (2.2K pull-up resistance), and is convenient for customers to use DIY.

4. On-board proximity switch interface, which can connect proximity switch conveniently and quickly, and support the selection of proximity switch NPN/PNP type

5. Onboard 2-way CNC fan, 1-way 4-wire fan interface

6. Onboard 3-way limit switch, 1-way BLTOUCH interface

7. USB power-on is selected through jumper cap to effectively isolate DC-DC and USB5V of main board

8. Proximity switch, CNC fan, 4-wire fan support VIN/12V/5V voltage selection

9. On-board SPI output interface. This port is reserved with 2 independent IO ports, which can be used for material breaking and blocking detection, or DIY operation of other functions

10. Add anti-flyback diode at heating rod and fan port to effectively protect MOS tube from being burnt by reverse voltage

11. The power interface has anti-reverse connection protection to prevent the board from burning when the customer connects the reverse power line during DIY

12. Onboard MAX31865, supporting the PT100/PT1000 selection of 2-wire/4-wire

13. Support CAN or USB communication, wherein the terminal resistance 120R of CAN can be selected through the jumper cap, and reserve the CAN expansion interface

14. The USB port is equipped with ESD protection chip to prevent the master controller from being broken down by the static electricity of the USB port

15. The factory is equipped with terminals, female springs, two-way studs and screws required by DIY, which greatly meets the customer's DIY requirements

16. It is used with BIGTREETECH EBB SB0000 CAN V1.0 and is perfectly compatible with VoronStealthBurner structure
