+MAX32672FTHR
+############
+
+Overview
+********
+The MAX32672FTHR is a rapid development platform that helps engineers quickly implement complex
+sensor solutions using the MAX32672 Arm® Cortex®-M4. The board also includes the MAX8819 PMIC for
+battery and power management. The form factor is a small, 0.9in by 2.6in, dual row header footprint
+that is compatible with Adafruit® FeatherWing peripheral expansion boards. The board includes
+an OLED display, a RGB indicator LED, and a user pushbutton. The MAX32672FTHR provides
+a power-optimized flexible platform for quick proof-ofconcepts and early software development
+to enhance time to market.
+
+The Zephyr port is running on the MAX32672 MCU.

+Programming and Debugging
+*************************
+
+Flashing
+========
+
+The MAX32625 microcontroller on the board is flashed with DAPLink firmware at the factory.
+It allows debugging and flashing the MAX32672 Arm Core over USB.
+
+Once the debug probe is connected to your host computer, then you can simply run the
+``west flash`` command to write a firmware image into flash.
+
+Debugging
+=========
+
+Please refer to the `Flashing`_ section and run the ``west debug`` command
+instead of ``west flash``.
