BIGTREETECH Kraken V1.0 motherboard is a 32-bit printer motherboard developed by the 3D printing team of Shenzhen Biq Technology Co., Ltd. for large machines. It has an onboard high-voltage and high-current stepper motor driver, which greatly simplifies the connection between the motherboard and the high-voltage driver, and also greatly saves money. The motherboard uses ID-designed silk screen printing to reduce the installation space in the chassis, and is matched with ID-designed heat sinks for auxiliary heat dissipation, which is both beautiful and practical.

Features
Adopts 32-bit ARM Cortex-M7 series STM32H723ZGT6 main control chip with a main frequency of 550 MHz;
The power chip uses TPS5450-5A, which supports DC12/24V power input. The chip output current is up to 5A, with a peak value of 6A, which perfectly supports the Raspberry Pi power supply;
The motherboard reserves a BOOT button, and users can update the motherboard boot program through DFU;
Add a protection circuit to the thermistor part to prevent the main control chip from burning due to leakage from the heating bed or heating rod;
CNC fans are available in 24V, 12V and 5V voltages, eliminating the need for customers to connect external transformer modules, thereby reducing the chance of motherboard damage;
Onboard two-channel MAX31865 supports dual-channel PT thermocouples, and supports two-wire or four-wire PT100/PT1000 options, which is convenient for customers to DIY;
The MCU firmware can be upgraded through a MicroSD card or through DFU through Klipper's make flash command;
Onboard 8-channel TMC2160 driven SPI mode, onboard DIAG function pin, which can be used by simply removing and plugging the jumper cap;
Reserved interfaces: material outage detection, shutdown after printing, Probe, RGB, I2C, servo interface, EXP1+EXP2, CAN, UART (SBC) interface, USBA power output interface, etc.;
Using high-performance MOSFET tubes to reduce heat generation;
Adopts replaceable fuse for easy replacement;
Two four-wire fan interfaces are reserved, 24V, 12V, and 5V voltages are optional, and can be used to connect water cooling devices;
Reserved proximity switch interface, supports NPN and PNP type selection, (24V, 12V, 5V) voltage optional;
An SPI expansion interface is reserved for customers using Klipper firmware to connect an external acceleration sensor for acceleration compensation;
TMC2160's MOS tube control power supply is provided by external DC12V, which reduces the driver's output impedance and reduces chip heat.
