Description
The BIGTREETECH Octopus Pro V1.0.1 (H723) is a high-performance 3D printer controller board engineered for advanced fabrication. Utilizing the ARM Cortex-M7 series STM32H723ZET6 microcontroller, it delivers exceptional processing stability and speed with a main frequency up to 550MHz and 1MB flash memory. This board is an excellent choice for Klipper high-speed printing, supporting both Marlin and RRF, and is fully compatible with Raspberry Pi / Octoprint operating systems, meeting the individual needs of DIY users and professionals alike.
Designed for robust multi-axis operation, the Octopus Pro V1.0.1 (H723) supports up to 8 powerful motor drivers with 5V level for stepper motor control, enhancing performance. It also accommodates a maximum 60V motor input voltage to boost motor power and reduce pulse loss, supporting STEP/DIR/UART/SPI modes. The board features up to 6 controllable fans and flexible 5V/12V power options for peripherals.
A crucial safety note regarding the STM32H723ZET6 chip pins: when entering DFU mode, the HE0 and HE2 heaters activate immediately. To prevent damage or hazards from prolonged heating, it is strongly advised not to enter DFU mode while the motherboard is powered by a 12V/24V supply. Firmware updates can be performed via DFU mode directly from a PC, though this method is generally not recommended for novice users without a bootloader.
