BTT Octopus 1.1 Pro Control Board
BTT Octopus 1.1 Pro Control Board
Features:
Main Control Chip】The main control board uses 32-bit ARM-level Cortex-M4 series STM32H723ZE chip with a frequency of up to 168MHz and the flash is 1MB.
【Support 60V Input】Supports up to 8 3D printer motherboards with a maximum 60V stepper motor. The motor drive power supply supports up to 60V input (only for the motor drive power supply).
【6 Controllable Fans】Up to 6 controllable fans, two normally open fans, and both support power supply voltage, 12V, 5V options.
【Update Firmware: Klipper/Marlin/RRF】Supports firmware update via DFU mode. This is where the firmware is sent to the board directly from the PC and does not require a bootloader however this method is not recommended for novice users as discussed later in this document.
【Level conversion IC】Supports proximity sensor, jumper optional pull-up resistor, supports more models, supports BL Touch.
Key Features:

- Rich interfaces: USB-C, Raspberry Pi header, ESP8266 WiFi support, CAN bus, multiple UART/SPI
- High I/O count for sensors, probes, RGB, fans, and expansions
- Built-in protections: over-temperature, over-current, and short-circuit safeguards
- Compatible with Marlin, Klipper, and RepRapFirmware (F446 variant optimized for Klipper & Marlin)
- Compact size: 160×100mm with standard 150×90mm mounting holes
*Please note: the H723 version does not include a fuse, while the F446 version includes a fuse.
