############
Overview
********
The MAX32666FTHR board is a rapid development platform to help engineers quickly implement battery
optimized Bluetooth® 5 solutions with the MAX32666 Arm® Cortex®-M4 processor with FPU. The board
also includes the MAX1555 1-Cell Li+ battery charger for battery management. The form factor is
a small 0.9in by 2.0in dualrow header footprint that is compatible with breadboards and
off-the-shelf peripheral expansion boards. The board also includes a variety of peripherals,
such as a micro SD card connector, 6-axis accelerometer/gyro, RGB indicator LED, and pushbutton.
This platform provides poweroptimized flexible for quick proof-of-concepts and early software
development to enhance time to market.

Programming and Debugging
*************************
Flashing
========
The MAX32666 MCU can be flashed by connecting an external debug probe to the SWD port.
SWD debug can be accessed through the Cortex 10-pin connector, JH2.
Logic levels are fixed to VDDIO (1.8V).
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.
.. note::
This board uses OpenOCD as the default debug interface. You can also use
a Segger J-Link with Segger's native tooling by overriding the runner,
appending ``--runner jlink`` to your ``west`` command(s). The J-Link should
be connected to the standard 2*5 pin debug connector (JH2) using an
appropriate adapter board and cable.
Debugging
=========
Please refer to the `Flashing`_ section and run the ``west debug`` command
instead of ``west flash``.
