Bigtreetech Octopus Pro controller board

The Bigtreetech Octopus Pro controller board, developed for your Voron or VzBot printer:

It supports Klipper and Marlin and provides space for up to 8 stepper drivers on one controller board in STEP/DIR, UART or SPI mode.

The main controller is a 32-bit ARM-level Cortex-M4 series processor with a frequency of up to 169MHz (STM32F429ZE, 1MB ROM), 180MHz (STM32F446ZET6, 512KByte ROM) or 550MHz (STM32H723ZE, 512KByte ROM)

Other specs are:

• Supply voltage: 15-28VDC (controller board and stepper drivers)
• Stepper input voltage: 12 – 48V (officially up to 60V but that’s extremely close to the built in capacitor specifications, so we cannot recommend going up to this limit) for stepper drivers
• 5 NTC plus one 2/4 wire PT100/PT1000 temperature sensor interfaces
• Supported Wifi Module: ESP8266 (MAX500k/s)
• Displays supported: BTT LFT screen, LCD12864, LCD2004, etc.
• PC communications interfaces: USB-C with configurable BAUD rate, CAN interface (for future use)
• Expansion interfaces: 2x Fil-DET, PWR-DET, PS-ON, BL Touch, etc.
• 6 PWM controllable fan interfaces, 3 selectable fan voltages
• Thermistor input protection
• 4 hotend heater connectors
• 6 endstop switch connectors
• Size: 16cmx10cm (mounting holes: 15cmx9cm)
