BIGTREETECH Octopus Pro V1.0 Control Board/ Mainboard 【Main Control Chip】The main control board uses 32-bit ARM-level Cortex-M4 series STM32H723ZE/ STM32F429ZE / STM32F446ZE chip with a frequency of up to 168MHz 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/RRF】Supports 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. BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D printers. BLTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on.
