Features: Using 32-bit, 64 MHz MCUs STM32G0B1CBT6 from the industry leading STM- ensures rock solid performance with CAN bus signaling that can support higher- data rates over longer distances without errors. The XT30 communication interface supports a maximum current of 10A, which is safer to use; with a 9.84ft CAN Bus wire, which is easy to use and saves steps- such as crimping terminals with crimping pliers; EBB SB2240 CAN onboard a TMC2240 . EBB SB2209 CAN onboard a TMC2209 . The TMC2240 features abundant- diagnostic and protection features short/open circuit protection, thermal shutdown, and under-voltage lockout. Due to internal optimizations, it can drive more current at lower temperatures, keeping your extruder running harder for longer. No need to solder anything thanks to the onboard header pins-. onboard MAX31865, Print hot and accurately with a PT100 or PT1000 temperature probe-. Configuration is simple using a DIP switch-. built-in ADXL345-,allows you to use the input shaping function for perfect printing Specifications: EBB SB2240 CAN: onboard TMC2240; SPI- drive working mode; EBB SB2209 CAN:onboard TMC2209 CAN UART drive working mode Microprocessor: Arm 32bit Cortex-M0+CPU STM32G0B1CBT6 64mhz Input voltage: DC12V-DC24V 9A Logic- voltage: 3.3V On board sensor: ADXL345 Fan interface: two CNC- fans FAN0 FAN1; 1-way 4-wire fan interface Maximum output current of fan interface: 1-1.5A Stepper- motor interface: EM Temperature sensor interface: 1 channel 100KNTC or PT1000 TH0; 1-way PT100/PT1000 optional USB communication interface: USB-typeC DCDC 5V output maximum current: for1A Expansion interface: EndStop ABL-RGB PT100/PT1000 USB interface CAN SPI- interface Note: Due to the light and screen difference, the item color may be slightly different from the pictures.
