# This file contains common pin mappings for the BIGTREETECH Manta M8P V2.0
# To use this config, the firmware should be compiled for the
# STM32H723 with a "128KiB bootloader" "25 MHz crystal"
# and "USB (on PA11/PA12)", "CAN bus (on PD0/PD1)" or Serial (on USART1 PA10/PA9).

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