Testing
-------

If you thinking for how to testing your new platform with PlatformiO, under VScode with plugin installed (Linux)
and how gather some essential information:

.. code-block:: cmd

/home/${USER}/.espressif/python_env/idf5.3_py3.10_env/bin/esptool.py --chip auto --baud 115200 --port /dev/ttyACM0 flash_id

Where most interested _essential_ output below, is like for security reason

1. WiFi Mac to add it to your network secure mac-access list
2. Chip and it's revision
3. Crystal base frequency
4. Flash size and onboard features with available PSRAM and Flash size
5. And other minor or major informations
