BIGTREETECH Octopus V1.1 - 3D Printer Motherboard

The BigTreeTech Octopus is one of the most comprehensive 3D printer motherboards available. The board is powered by a powerful 32-bit processor and runs on Marlin or Klipper firmware. The firmware can be easily uploaded and updated with an SD card (not included). You can print from a USB stick or directly from a PC or Raspberry Pi via a USB cable. Moreover, extra modules can be connected for additional functions, such as a Power-off resume kit, Auto shutdown after printing, Filament run-out sensor, RGB LEDs (WS2812/neopixel), etc.
