+# This file contains pin mappings for the stock Elegoo Neptune 3 Pro (ZNP Robin Nano_DW V2.2)
+# To use this config, during "make menuconfig" select the  STM32F401 with a
+# "32KiB bootloader" and serial (on USART1 PA10/PA9) communication.
+
+# Note that the "make flash" command does not work with ZNP Robin boards.
+# After running "make", rename the out/klipper.bin file to out/ZNP_ROBIN_NANO.bin
+# Copy the file out/ZNP_ROBIN_NANO.bin to an SD card formatted to FAT32
+# and then restart the printer with the SD card inserted.
+
+# See docs/Config_Reference.md for a description of parameters.
