+# This file contains common pin mappings for the BIGTREETECH SKR
+# MINI. To use this config, the firmware should be compiled for the
+# STM32F103 with a "28KiB bootloader" and USB communication.
+
+# The "make flash" command does not work on the SKR mini. 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 with that SD card.
+
+# See docs/Config_Reference.md for a description of parameters.
+
+# Note: This board has a design flaw in its thermistor circuits that
+# cause inaccurate temperatures (most noticeable at low temperatures).
