Motivation

Provide concrete, web-validated recommendations for which ESP32 DevKit boards are best suited for the RTC phone MVP (combiné + clavier + audio) to make hardware selection easier.
Surface PlatformIO board IDs and official references so users can start a project quickly and pick an appropriate dev kit for later audio/Bluetooth work.

Description

Added docs/solutions_rtc_phone_esp32.md with a short-listed set of recommended dev kits (ESP32-DevKitC esp32dev, ESP32-S3-DevKitC-1 esp32-s3-devkitc-1, NodeMCU-32S nodemcu-32s, LOLIN32 lolin32), a note about ESP32-C3 suitability, and links to Espressif / PlatformIO docs.
Updated README.md to include quickstart steps and a pointer to the new dev kit selection guidance.
Kept existing PlatformIO skeleton (platformio.ini) and minimal prototype firmware (src/main.cpp) from the project scaffold to preserve the working starting point for the MVP.

Testing

Verified referenced Espressif and PlatformIO documentation URLs returned HTTP 200 using curl checks, and all listed links responded with status 200 (success).
Ran git operations to stage and commit the changes and verified the commit completed successfully.
Attempted a PlatformIO build was not executed in this environment because the pio CLI is not installed, so no local build was run (external pio build not tested here).

Codex Task

### Motivation - Provide concrete, web-validated recommendations for which ESP32 DevKit boards are best suited for the RTC phone MVP (combiné + clavier + audio) to make hardware selection easier. - Surface PlatformIO board IDs and official references so users can start a project quickly and pick an appropriate dev kit for later audio/Bluetooth work. ### Description - Added `docs/solutions_rtc_phone_esp32.md` with a short-listed set of recommended dev kits (ESP32-DevKitC `esp32dev`, ESP32-S3-DevKitC-1 `esp32-s3-devkitc-1`, NodeMCU-32S `nodemcu-32s`, LOLIN32 `lolin32`), a note about ESP32-C3 suitability, and links to Espressif / PlatformIO docs. - Updated `README.md` to include quickstart steps and a pointer to the new dev kit selection guidance. - Kept existing PlatformIO skeleton (`platformio.ini`) and minimal prototype firmware (`src/main.cpp`) from the project scaffold to preserve the working starting point for the MVP. ### Testing - Verified referenced Espressif and PlatformIO documentation URLs returned HTTP 200 using `curl` checks, and all listed links responded with status `200` (success). - Ran `git` operations to stage and commit the changes and verified the commit completed successfully. - Attempted a PlatformIO build was not executed in this environment because the `pio` CLI is not installed, so no local build was run (external `pio` build not tested here). ------ [Codex Task](https://chatgpt.com/codex/tasks/task_e_698f1c841f888331bc152e21bf583a5b)
