BIGTREETECH Octopus Pro V1.0 Controller Board New Features
-
【Main Control Chip】The main control adopts the 32-bit ARM Cortex-M4 series STM32F446ZET6 chip with a frequency of up to 180 MHz. The external crystal oscillator is 12MHz.
-
【About Using Firmware】Support the use of Marlin2.0, killper, RRF three types of firmware. Please note: STM32F446ZET6 MCU flash memory space is 512k, so only some functions can be used when using RRF firmware.
-
【Stepper Motor】The Octopus Pro 3D printing motherboard can support up to 8 stepper motor drivers, and the motor drive power supply supports up to 60V input (only motor drive power supply).
-
【Support Proximity Sensor】Support proximity sensor, jumper optional pull-up resistor, support more models. This function can be sensed without touching the hot bed, while BLTouch needs touch sensing.
-
【High Temperature Test】The onboard MAX31865 can support 2/4-wire PT100/PT1000 temperature measurement without welding (the soldering resistance can also support 3-wire PT100/PT1000 temperature measurement)
About BIGTREETECH Octopus Pro V1.0 Controller Board New
BIGTREETECH Octopus Pro V1.0 New Upgrade Control Board About the difference between the main control chip STM32F446ZET6 and STM32F429ZGT6: 1. The main control frequency of F446 is 180MHz, and the main control frequency of F429 is 168MHz; 2. The external crystal oscillator of F446 is 12MHz, and the external crystal oscillator of F429 is 8MHz; 3. F446's flash memory space is smaller than F429, F446 flash memory is 512K, F429 is 1MB; when they use RRF firmware, F446 has limited space, so some functions of RRF firmware are deleted. Both Marlin2.0 and Killer can be used normally.
