# This file contains common pin mappings for the BIGTREETECH SKR mini
# E3 v1.2. To use this config, the firmware should be compiled for the
# STM32F103 with a "28KiB bootloader". Also, select "Enable extra
# low-level configuration options" and configure "GPIO pins to set at
# micro-controller startup" to "!PC13".

# The "make flash" command does not work on the SKR mini E3. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the SKR
# mini E3 with that SD card.

# See the example.cfg file for a description of available parameters.
