BIGTREETECH Octopus V1.1 Control Board 32bit Compatible TMC2209, TMC2208 Stepper Driver, Support DIY Klipper Firmware and Raspberry Pi Online Printing for Voron V2.4 Upgrade 3D Printer

Uses a 32-bit ARM Cortex-M4 series STM32F446ZET6 main control chip with a core frequency of 180MHz.

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.

Interfaces with a Raspberry Pi using emulated serial over USB or direct UART to any of the serial ports on the board, to realize Klipper Firmware and Raspberry Pi Online Printing.

Supports BLTouch, locked-rotor detection, shutdown after printing, resume printing after power failure, CAN bus, U disk function, IIC expansion; at the same time reserved WIFI interface, PT100 thermistor interface (optional, Only reserved interfaces, customers need to purchase chip welding, please pay attention.), dual Z-axis printer.

Uses high-performance MOSFETs to increase heating efficiency while also reducing heat generation on the motherboard.
