# This file contains common pin mappings for the BigTreeTech GTR.
# To use this config, the firmware should be compiled for the
# STM32F407 with a "32KiB bootloader".
# The "make flash" command does not work on the GTR. Instead,
# after running "make", copy the generated "klipper/out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the GTR
# with that SD card.
# See docs/Config_Reference.md for a description of parameters.
