OCTOPUS MOTHERBOARD FEATURES –

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

2. Interfaces with a Raspberry Pi using emulated serial over USB or direct UART to any of the serial ports on the board.

3. Supports running Klipper and Marlin.

4. Supports up to 4 hotend heaters

5. Supports 12V or 24V inputs with built-in 12V, 5V, and 3.3V regulators to provide rails for peripheral use.

6. Supports multiple languages such as English and Simplified Chinese and can easily switch between different languages

7. Supports “print from SD card” and “print via USB OTG” using the integrated USB-A port.

8. Supports BL Touch and various other ABL sensors.

9. Supports CAN-BUS using a 6P6C RJ11 interface, which offers the board the ability to interface with future expansion modules.

10. Supports StallGuard for sensorless homing with TMC drivers.

11. Supports the shutdown after the printing function.

12. Supports the power loss print resume function
