+# This file contains pin mappings for the Creality Sermoon D1 with
+# Rev. 4.3.1 Motherboard.
+
+# To use this config, during "make menuconfig" select the STM32F103
+# with a "28KiB bootloader" and serial (on USART1 PA10/PA9)
+# communication.
+
+# Flash this firmware by copying "out/klipper.bin" to a SD card and
+# turning on the printer with the card inserted. The firmware
+# filename must end in ".bin" and must not match the last filename
+# that was flashed.
+
+# See docs/Config_Reference.md for a description of parameters.
