Product Profile
BIGTREETECH Kraken V1.0 is a 32-bit motherboard for large printers. It comes
with onboard high-voltage, high-current stepper motor drivers, significantly
simplifying the connection between the motherboard and high-voltage drivers and
saving space in the chassis. The board uses silkscreened ID design with an ID-
design heat sink for aesthetics and practical cooling.
Features Highlights
Utilizes a 32-bit ARM Cortex-M7 series STM32H723ZGT6 MCU with a main
frequency of 550 MHz.
TPS5450-5A power chip, supporting DC12/24V power input. This chip
provides an output current of up to 5A, peaking at 6A, perfectly supporting
Raspberry Pi power supply.
The motherboard has a reserved BOOT button, allowing users to update the
bootloader via DFU mode.
The thermistor circuit is protected to prevent MCU damage from shorted
heated bed and heater cartridge connections;
Selectable voltage (24V, 12V, 5V) for PWM fan, eliminating the need for
external voltage conversion modules, thereby reducing the likelihood of
motherboard damage.
Onboard two MAX31865 modules, supporting dual PT thermocouples and
compatible with two or four-wire PT100/PT1000, facilitating DIY usage for
customers.
Firmware can be upgraded via MicroSD card or through the Klipper's `make
flash` command via DFU.
Onboard 8 TMC2160 drivers in SPI mode with DIAG function pins; simply
plug and unplug jumpers for easy use.
Reserved interfaces for Filament Detection, Auto Power-Off, Probe, RGB, I
2
C,
Servo, EXP1+EXP2, CAN, UART (SBC), and USB A power output.
High-performance MOSFETs to reduce heat generation.
Replaceable fuses for easy replacement.
2x 4-pin fan interfaces with selectable voltages of 24V, 12V, and 5V, also
suitable for water cooling setups.
Onboard proximity switch port, supports NPN and PNP types, 24V, 12V, 5V
voltage selectable;
