WUQ Octopus V1.1 32-bit control board office equipment

SKU CH-595J-631NF

32-bit control board with ARM Cortex-M4 microcontroller at 180MHz, 512Kb flash, eight driver sockets, six PWM fans and CAN Bus for Klipper or Marlin 3D printers

  • TypeOffice Machines - Multifunctional
  • 32-bit STM32F446 at 180 MHz for fast motion control
  • 8 TMC2209 driver sockets support up to 8 axes
  • CAN bus via Ethernet connector simplifies expansion board wiring
  • 6 PWM-controlled fans with 5 V, 12 V or 24 V selectable voltage
  • Runs Klipper or Marlin with BTT Pi V1.2 or Pi 2

32-bit control board for 3D printers

The WUQ Octopus V1.1 uses an ARM Cortex-M4 STM32F446ZET6 microcontroller running at 180MHz with 512Kb flash ROM. It accepts only 24V input and provides eight driver sockets for TMC2209 stepper motor drivers. The board is designed for Voron 2.4, CoreXY and VZbot machines running Klipper or Marlin firmware.

Replaces 8-bit boards when CAN Bus expansion is

Upgrading from an 8-bit board adds 32-bit processing and a CAN Bus link via an ethernet connector for simple expansion board attachment. The jump is worth it when the printer requires six controllable PWM fans plus two additional fans with selectable 5V, 12V or 24V voltage, or when a BTT Pi V1.2 or Pi 2 will host Klipper.

Firmware updates via USB Type C or DFU mode

A USB Type C port powers the MCU for programming when the jumper cap is fitted; otherwise the 24V supply must be on. DFU mode writes firmware directly from a PC without a bootloader and is not recommended for novice users. The board also supports Eddy V1.0, BLTOUCH, Microprobe, SFS V2.0 filament sensor, power loss detection and TFT35 or TFT50/70 displays.

Questions about this item

What voltage power supply does the Octopus V1.1 board require?

The board only supports a 24 V input; a 12 V supply is not allowed and will not power the board.

How do I power the MCU for a firmware update over USB?

Fit the jumper cap onto the 5 V USB power pin, then connect the Type C port to the PC; remove the jumper when running from the main 24 V supply.

Which stepper drivers are compatible with the eight driver sockets?

The sockets accept TMC2209 modules, giving up to eight axes of silent 32-bit motor control.
