There are 2 variants of the Octopus Pro:

• Octopus Pro F446 (180 Mhz ARM-Cortex-M4 CPU & 512 KB flash memory)
• Octopus Pro F429 (168 Mhz ARM-Cortex-M4 CPU & 1MB flash memory)

This is the F429 – While having a slight run speed disadvantage, this should be the board of choice for those looking for some serious firmware flexibility.

8 Powerful Stepper Drivers

8 powerful stepper drivers provide more stable operation.
5V level for stepper motor drivers and 60V motor input voltage contribute to better performance and reduction of pulse loss.

168Mhz ARM Cortex-M4 CPU or 180Mhz ARM Cortex-M4 CPU

BIGTREETECH Octopus Pro uses a 32-bit ARM Cortex-M4 series chip with a core frequency of 168 or 180 MHz, providing enough power to realise even the most demanding applications and ideas.
