+# This file contains common pin mappings for the Two Trees Sapphire
+# Pro printer from 2020. To use this config, the firmware should be
+# compiled for the STM32F103. When running "make menuconfig", enable
+# "extra low-level configuration setup", select the 28KiB bootloader,
+# disable "USB for communication", select USART3 for the "Serial
+# Port", and set "GPIO pins to set at micro-controller startup" to
+# "!PC6,!PD13".
+
+# Note that the "make flash" command does not work with the Sapphire
+# Pro. After running "make", run the following command:
+#   ./scripts/update_mks_robin.py out/klipper.bin out/Robin_nano35.bin
+# Copy the file out/Robin_nano35.bin to an SD card and then restart the
+# printer with that SD card.
+
+# See the example.cfg file for a description of available parameters.
