- Original AWA implementation commit:
  <https://github.com/awawa-dev/HyperSerialWLED/commit/608da5a0e4048332983b6f99351860dd3f6d212d>

## ESP32 firmware framework

The firmware is linked with:

- Arduino core for ESP32 2.0.6:
  <https://github.com/espressif/arduino-esp32/tree/2.0.6>
- ESP-IDF components supplied by that Arduino core:
  <https://github.com/espressif/esp-idf>
- Mbed TLS supplied by ESP-IDF:
  <https://github.com/Mbed-TLS/mbedtls>

Arduino-ESP32 is licensed under LGPL-2.1-or-later. See
`licenses/LGPL-2.1.txt`.

ESP-IDF and Mbed TLS are primarily licensed under Apache-2.0. See
`licenses/Apache-2.0.txt`. Individual ESP-IDF components can contain
additional permissive notices; their source and notices are available from
the upstream ESP-IDF repository.

The complete project source, build configuration, and scripts required to
rebuild the firmware are available at:
<https://github.com/Serjio193/lg_apa102>

## Build-time tools

The following tools are used to create release artifacts but are not embedded
as executable code in the firmware:

- esbuild 0.25.12, MIT License, copyright (c) 2020 Evan Wallace.
  See `licenses/esbuild-MIT.txt`.
- PyCryptodome, used by `tools/sign_artifact.py`.
  See `licenses/PyCryptodome-LICENSE.rst`.

## User-owned legacy source

The signed Recovery/OTA design was adapted from the repository owner's
`Serjio193/legacy-bridge` project. It is not listed as a third-party component
because both repositories are owned by the same author and no external
license notice is present in that source repository.
