+# This file contains pin mappings for a full Ratrig V-Minion kit
+# with an Octopus Pro v1.1 board.
+#
+# This will not work with RatOS
+#
+# To use this config, during "make menuconfig" select the STM32F446
+# with a "32KiB bootloader", USB (on PA11/PA12) communication, and
+# a "12MHZ Crystal"
+#
+# Flash this firmware on the MCU by copying "out/klipper.bin" to an SD
+# card and turning the printer on with the card inserted. The firmware
+# filename must be named "firmware.bin"
+#
+# See docs/Config_Reference.md for a description of parameters.
