BIGTREETECH Octopus V1.1 Control Board For Voron 2.4

Properties:
It uses a 32-bit ARM Cortex-M4 control chip of the STM32F446ZET6 or STM32F407ZE series. Both chips support Marlin and Klipper at high frequency.

-Strong DIY support?This motherboard supports up to 8 stepper drivers with a total of 9 stepper driver outputs; 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. Choose from Vin, 12V or 5V.

- Motherboard expansion function?BLTouch support, locked rotor detection, shutdown after printing, print resume after power failure, CAN bus, U disk function, IIC extension; also dedicated WIFI interface, PT100 thermistor interface (optional), dual Z-axis printer.

- Features of the TMC2209 Stepper Driver The TMC2209 stepper driver does not lose steps easily and is in ultra-quiet mode; the module has a large heat dissipation pad area, which can reduce the temperature of the driver when working; the module supports three modes: STEP/DIR and UART.

- TMC2209 TMC Driver Mode Motor drivers can be used in SPI or UART mode by simply setting the built-in jumpers under each motor driver. In addition, you can use the built-in jumper to connect or disconnect the TMC DIAG pin, allowing you to use hard end stops or sensorless guidance without having to cut any pins.
