BIGTREETECH Octopus Pro Motherboard for CR10 3D printer Control Board Upgrade Support Marlin 2.0 Klipper RRF TMC2209 TMC2208 DRV8825 TFT35 Display 12864LCD ect (STM32F429ZGT6)

Two Versions of MCUs Available: 32b ARM Cortex-M4 MCU STM32F446ZET6 with a clock frequency of 180MHz and 512k of flash memory, being this version the most advisable for Klipper or Marlin firmwares; MCU of 32b ARM Cortex-M4 STM32F429ZGT6 with a clock frequency of 168Mhz and 1MB of flash memory, this version being the most recommended for RRF firmwares.
Firmware: Not plug and play, You need to compile your own marlin or klipper for it. Features: Interface for Raspberry Pi both by USB and UART (by GPIO)Up to 4 hotends available. Up to 8 high voltage drivers or normal with new protection electronics. Independent power supply for motors, hot bed and electronics. Up to 6 controllable fans and 2 without control, with the possibility of selecting the working voltage between Vin, 12V and 5V.
Difference from Octopus V1.1: Support for high voltage (HV) drivers has been added, specifically up to theoretical 60V, although we recommend working with 48V systems; Improved driver control electronics, with new integrated that promise to improve the quality and management of their use; Standard inclusion of an amplifier for PT100 sensors. Remember that the normal version of the Octopus has the pre-installation.
