# This file contains common pin mappings for the BigTreeTech Octopus
# and Octopus Pro boards. To use this config, start by identifying the
# micro-controller on the board - it may be an STM32F446, STM32F429,
# or an STM32H723.  Select the appropriate micro-controller in "make
# menuconfig" and select "Enable low-level configuration options". For
# STM32F446 boards the firmware should be compiled with a "32KiB
# bootloader" and a "12MHz crystal" clock reference. For STM32F429
# boards use a "32KiB bootloader" and an "8MHz crystal". For STM32H723
# boards use a "128KiB bootloader" and a "25Mhz crystal".

# See docs/Config_Reference.md for a description of parameters.
