Kraken Control Board for 3D printers

The BIGTREETECH Kraken Control Board is a new desktop server chassis designed for DIY builders assembling high-performance CoreXY machines such as the Voron 24. It integrates an STM32H723ZGT6 MCU running at 550 MHz alongside eight onboard TMC2160 stepper drivers in SPI mode. Two MAX31865 modules provide dual thermocouple support for PT100 or PT1000 sensors in two-wire or four-wire configurations.

Check firmware and wiring compatibility

Before ordering, verify that your chosen firmware (Klipper, Marlin or RRF) supports the STM32H723 platform and the eight-driver SPI layout. Confirm your stepper motors are rated for up to 60 V operation and that your existing wiring harnesses match the JST CANbus sockets for EBB SB2209 or SB2240 toolhead boards. Ensure your power supply can deliver the required 12 V or 24 V rails for the selectable fan and proximity-switch voltages.

Fits a Voron 24 IDEX build

The board reserves two CANbus ports for direct connection to toolhead expansion boards, freeing the main MCU from extra UART traffic. Four-wire fan headers with 5 V, 12 V or 24 V selection simplify water-cooling integration without additional converters. An SPI extension header allows Klipper users to attach an external accelerometer for input-shaping calibration, while the proximity-switch interface accepts both NPN and PNP sensors at selectable voltages.

Questions about this item

What comes in the box and what must I source separately for a complete Kraken build?

The box contains the Kraken control board with eight onboard TMC2160 drivers, two MAX31865 modules and JST sockets for CANbus. You must buy EBB SB2209 or EBB36 or EBB42 CAN boards (two), a BTT Pi, and an HDMI5 or HDMI7 cable separately.

Which EBB CAN board variant — SB2209, EBB36 or EBB42 — should I choose for dual IDEX?

All three are listed as compatible; pick the one that matches your stepper motor frame size and wiring preference for the Voron24 Core XY IDEX setup.

What does the 550 MHz STM32H723ZGT6 mean for real-time printer performance?

The Cortex-M7 MCU runs at 550 MHz, giving fast step-pulse generation and headroom for Klipper acceleration compensation with an external sensor on the SPI extension port.
