BTT Octopus Controller Board / 3D Printer Control System

This is one sweet board, perfect for a Voron build. ARM Cortex-M4 STM32F446ZET6 32-bit microcontroller at 180MHz Support for Klipper and Marlin firmwares Interfaces for Raspberry Pi (USB and UART by GPIO) Up to 4 hotends available Integrated DCDC to provide 12V(4A), 5V(8A) and 3.3V(1A) power supply Up to 6 controllable fans and 2 without control with the possibility of voltage selection (Vin, 12V and 5V) Protection against short circuit on fans, something very important since it is one of the most common problems USB-C connector that allows serial emulation to print using USB Compatibility with almost any screen High performance MOSFETs, improve heating speed and efficiency Protection fuses easily replaceable Double motor output for the Z axis Improvements in the bootloader, supporting the update by USB (recommended) and DFU (advanced users) 32K EEPROM (AT24C32) Connectors for RGB LEDs and Neopixel Connector for WiFi interface  PT100 interface (requires INA8 amplifie
