## Hardware

Platform Espressif 8266: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

Microcontroller | ESP8266
Frequency | 80MHz
Flash | 1MB
RAM | 80KB
Vendor | WEMOS

## Configuration

Please use `d1_mini_lite` ID for board option in “platformio.ini” (Project Configuration File):

    [env:d1_mini_lite]
    platform = espressif8266
    board = d1_mini_lite

You can override default WeMos D1 mini Lite settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest d1_mini_lite.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:d1_mini_lite]
    platform = espressif8266
    board = d1_mini_lite

    ; change microcontroller
    board_build.mcu = esp8266

    ; change MCU frequency
    board_build.f_cpu = 80000000L

## Uploading

WeMos D1 mini Lite supports the next uploading protocols:

- `espota`

- `esptool`

Default protocol is `esptool`

You can change upload protocol using upload_protocol option:

    [env:d1_mini_lite]
    platform = espressif8266
    board = d1_mini_lite

    upload_protocol = esptool

## Debugging

PIO Unified Debugger currently does not support WeMos D1 mini Lite board.
