+# This file contains common pin mappings for the Duet3 Mini 5+. To use
+# this config, the firmware should be compiled for the ATSAMD51P20
+# with a "25Mhz crystal", "16KiB bootloader", and USB communication.
+
+# To flash the board, double tap the board's reset button to enter the
+# bootloader and then run: make flash FLASH_DEVICE=/dev/ttyACM0
+
+# See docs/Config_Reference.md for a description of parameters.
