BIGTREETECH Octopus PRO V1.0/V1.1 Motherboard 32-Bit Control Board Upgrade Octopus TMC5160T TMC2208 VS Ender3 V2 For CR10

【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.

Octopus Pro offers different versions of MCUs to meet the individual needs of DIY users.

ARM Cortex-M7 series, STM32H723ZET6, main frequency up to 550MHz, supports Marlin and Klipper, the best choice for Klipper high-speed printing. However, due to the limitation of 512kb flash, currently, RRF is not supported.

ARM Cortex-M4 series, STM32F429ZGT6, 180MHz main frequency, supports Marlin and Klipper, and with 1Mb flash, it can support RRF full function.

ARM Cortex-M4 series, STM32F446ZET6, 180MHz main frequency, supports Marlin and Klipper. However, due to the limitation of 512kb flash, it can only use the BTT custom version of RRF cutting off some functions.
