About this item

The BIGTREETECH BTT Octopus Pro V1.0.1 (F446) is a high-performance 32-bit 3D printer control board designed for complex and multi-extruder machines. Powered by the STM32F446ZET6 microcontroller, which runs at 180 MHz, this board offers a perfect balance of processing power and reliability for demanding 3D printing tasks. Supporting up to 8 stepper motor drivers, the Octopus Pro allows control of multiple axes and extruders, making it suitable for CoreXY, multi-material, or multi-tool 3D printers. It supports both SPI and UART communication protocols for stepper drivers, offering compatibility with popular Trinamic drivers like the TMC2209, TMC5160, and others. With robust connectivity options—including CAN bus, multiple fan outputs, thermistor inputs, BLTouch support, filament sensors, and dedicated Raspberry Pi headers—the Octopus Pro integrates seamlessly with firmware like Marlin, Klipper, and RepRapFirmware. Its advanced power management includes MOSFET outputs for heaters and fans with built-in protection, ensuring safe and efficient operation. The Octopus Pro V1.0.1 (F446) is ideal for users looking to upgrade to a powerful, flexible, and future-proof control board capable of handling complex printing setups with ease.
