ESPresso Lite 2.0
=================

.. contents::

Hardware
--------

Platform :ref:`platform_espressif8266`: ESP8266 is a cost-effective and highly integrated Wi-Fi MCU with built-in TCP/IP networking software for IoT applications. ESP8266 integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM.

.. list-table::

  * - **Microcontroller**
    - ESP8266
  * - **Frequency**
    - 80MHz
  * - **Flash**
    - 4MB
  * - **RAM**
    - 80KB
  * - **Vendor**
    - `ESPert <http://www.espert.co?utm_source=platformio.org&utm_medium=docs>`__


Configuration
-------------

Please use ``espresso_lite_v2`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:espresso_lite_v2]
  platform = espressif8266
  board = espresso_lite_v2

You can override default ESPresso Lite 2.0 settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `espresso_lite_v2.json <https://github.com/platformio/platform-espressif8266/blob/master/boards/espresso_lite_v2.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:espresso_lite_v2]
  platform = espressif8266
  board = espresso_lite_v2

  ; change microcontroller
  board_build.mcu = esp8266

  ; change MCU frequency
  board_build.f_cpu = 80000000L


Uploading
---------
ESPresso Lite 2.0 supports the following uploading protocols:

* ``espota``
* ``esptool``

Default protocol is ``esptool``

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

.. code-block:: ini

  [env:espresso_lite_v2]
  platform = espressif8266
  board = espresso_lite_v2

  upload_protocol = esptool

Debugging
---------
:ref:`piodebug` currently does not support ESPresso Lite 2.0 board.
