+# Paste here and save your klipper configuration
+# This file contains standard pin mappings for the stock Elegoo Neptune 2 with a
+# ZNP Robin Nano (v 1.2 and v1.3) board.
+# For the 1.2 board:
+#   - Compile with the processor model STM32F103.
+#   - Enable "extra low-level configuration options"
+#   - Select the 28KiB bootloader,
+#   - Select (Serial (on # USART3 PB11/PB10) for the communication interface.
+# Note that the "make flash" command does not work with ZNP Robin boards. After
+# running "make", run the following command:
+# ./scripts/update_mks_robin.py out/klipper.bin out/elegoo.bin
+# 
+# For the 1.3 board:
+#   - Compile with the processor model STM32F407.
+#   - Enable "extra low-level configuration options"
+#   - Select the 32KiB bootloader,
+#   - Select (Serial (on # USART3 PB11/PB10) for the communication interface.
+# Note that the "make flash" command does not work with ZNP Robin boards. After
+# running "make", run the following command:
+# cp out/klipper.bin out/elegoo.bin
+# 
+# Copy the file out/elegoo.bin to an SD card and then restart the printer with
+# that SD card.
+# See docs/Config_Reference.md for a description of parameters.
