+# This file contains common pin mappings for the Alfawise U30 printer.
+# To use this config, the firmware should be compiled for the
+# STM32F103. When running "make menuconfig", enable "extra low-level
+# configuration setup", select the 64KiB bootloader, disable "USB for
+# communication", and set "GPIO pins to set at micro-controller
+# startup" to "!PC4,!PD12".
+
+# The "make flash" command does not work on the Alfawise U30. Instead,
+# after running "make", copy the generated "out/klipper.bin" file to a
+# file named "project.bin" on an SD card and then restart the Alfawise
+# with that SD card.
+
+# See the example.cfg file for a description of available parameters.
