4. Interfaces with a Raspberry Pi using emulated serial over USB or direct UART to any
of the serial ports on the board.
5. Supports up to 4 hotend heaters.
6. Provides separate power inputs for motors, bed heating and logic/fans/hotends.
7. Supports 12V or 24V supply inputs (12V only supported on motor and bed. Logic
must be > 14.1V and < 28V) with built in 12V (4A), 5V (8A) and 3.3V (1A) regulators
to provide rails for peripheral use.
8. Up to 6 PWM fans and 2 always-on fans with the ability to individually select the
voltage rail that will drive each fan. Select from Vin, 12V or 5V.
9. Flyback protection on PWM fan ports – Many people find that their fan ports become
damaged after some time when using larger fans. This is because of the inductance
in the fan coils. The octopus includes flyback protection on each fan port which will
protect the FETs from damage caused by turning the fans on and off.
10. Includes USB-C interface which supports an emulated serial port that allows printing
via USB.
11. Supports all versions of BIGTREETECH TFT screens and LCD12864 screens.
12. Supports multiple languages such as English and Simplified Chinese and can easily
switch between different languages (when using the BTT TFT).
13. Includes a bootloader that allows firmware upgrades via the SD card. This offers a
simple, efficient, and convenient way to update the firmware.
14. Uses high-performance MOSFETs to increase heating efficiency while also reducing
heat generation on the motherboard.
15. Uses easily replaceable fuses
16. Supports “print from SD card” and “print via USB OTG” using the integrated USB-A
port.
