Description

This is BIGTREETECH BTT Octopus Pro V1.0.1 (H723) 3D Printer Controller Board.
BIGTREETECH Octopus Pro V1.0.1（H723) board adopts the ARM Cortex-M7 series, STM32H723ZET6, main frequency up to 550MHz, Processing is more stable and fast. Supports Marlin and klipper, the best choice for Klipper high-speed printing meet the individual need of DIY users, support Operation systems Raspberry Pi / Octoprint. Support 8 axis powerful motor driver ，support 5V level for stepper motor driver ,better performance. support max 60V motor input voltage to improve motor power ,reduce pulse losing. Support STEP/DIR/UART/SPI Mode.
Octopus Pro (H723) has a unique feature with its STM32H723ZET6 chip pins. When the chip enters DFU mode, the HE0 and HE2 will immediately start working. To prevent any damage or safety hazards resulting from prolonged heating of the heater cartridge, it is highly recommended not to enter DFU mode while the motherboard is powered by a 12/24V power supply. Following are the characteristics of BIGTREETECH Octopus Pro V1.0.1 (H723).

Main Control Chip: The main control board uses 32-bit ARM-level Cortex-M4 STM32H723ZE?and the flash is 1MB.
Support 60V Input: Supports up to 8 3D printer motherboards with a maximum 60V stepper motor. The motor drive power supply supports up to 60V input (only for the motor drive power supply).
6 Controllable Fans: Up to 6 controllable fans, two normally open fans, and both support power supply voltage, 12V, 5V options.
Update Firmware: Klipper/Marlin/RRFSupports firmware update via DFU mode. This is where the firmware is sent to the board directly from the PC and does not require a bootloader however this method is not recommended for novice users as discussed later in this document.
Level conversion IC: Supports proximity sensor, jumper optional pull-up resistor, supports more models, supports BL Touch.
