BIGTREETECH Octopus V1.1 BTT Motherboard

New Arrival Octopus Pro V1.1! With Motor input voltage support up to 60V, which mean u can now use TMC5160 HV, MAX31865 chip for extra PT1000 thermistor and also MAX8 HV Drive.

Note: Octopus Pro V1.1 F446 has 512K Flash thus it would be cut down the features of RRF firmware. if not using RRF firmware, this is the perfect board for Marlin & Klipper.

🐙【Main Control Chip】Uses a 32-bit ARM Cortex-M4 series STM32F446ZET6 main control chip with a core frequency of 180MHz.
🐙【Strong DIY Support】This motherboard supports up to 8 stepper drivers with 9 stepper driver outputs in total; And up to 6 PWM fans and 2 always-on fans with the ability to individually select the voltage rail that will drive each fan. Select from Vin, 12V or 5V.
🐙【Increase Protection Function】Uses high-performance MOSFETs to increase heating efficiency while also reducing heat generation on the motherboard. Supports “print from SD card” and “print via USB OTG” using the integrated USB-A port.
🐙【BLTouch Auto Leveling Sensor】BLTouch is an auto leveling sensor for 3D Printers based on open-source.Simple, Smart, High-precision.It could work with any kinds of bed materials, such as glasses, woods, metals, and so on.
🐙【What You Can Receive】BIGTREETECH Octopus V1.1 Motherboard*1, Type C Cable*1, Rubber Duck*1, Exquisite Packaging Box*1.
