BIGTREETECH Octopus Pro V1.0 (STM32F446) without Drivers for 3D Printer

This is most definitely overkill for a simple 3D printer, however if you are thinking about upgrading your 3D printer, this is the board to go with. It has so many ports available to use. SPI, I2C, UART, analog and digital inputs and outputs, 8 motor driver ports with protector. It also comes with 6 CNC-fan, 2 normal fan interfaces, 4 cartridge heater ports, 6 limit switch ports, 2 filament sensor ports and supports for NTC100K & PT100/PT1000 high-temperature thermistors. The Type-C USB interface for online printing, CANBus with RJ11 interface and onboard MAX31865 RTD to digital converter.

Octopus Pro V1.0 with ARM Cortex-M4 series STM32F446ZET6 supports Marlin and Klipper and runs 180MHz main frequency. However, due to the limitation of 512kb flash, it can only use the BTT custom version of RRF cutting off some functions; click here for more detail.

Note: This motherboard DOESN'T come with stepper motor drivers; you might need to purchase it separately. 

• 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.

• 1 x BIGTREETECH Octopus Pro V1.0 (STM32F446) without Stepper Motor Drivers
