What is this?
The Arduino core for the ESP32 family of SoCs — it lets you write and flash programs for ESP32-series chips using the standard Arduino API instead of raw ESP-IDF.
The Arduino core for the ESP32 family of SoCs — it lets you write and flash programs for ESP32-series chips using the standard Arduino API instead of raw ESP-IDF.Is this the Arduino IDE itself, or something I add to it?Not the IDE itself: it is a board support core you add on top of the Arduino toolchain, and it can also be embedded into ESP-IDF projects as a component.

No — ESP32-C2 and ESP32-C61 are not covered by the prebuilt packages: they require the Arduino-as-ESP-IDF-component route or rebuilding the static libraries.Can I build ESP-IDF projects that include this core?Yes — one documented setup mode is using Arduino as an ESP-IDF component, so the Arduino API is layered inside a native ESP-IDF project. That is also the required route for ESP32-C2 and ESP32-C61.

That is also the required route for ESP32-C2 and ESP32-C61.Is the core still actively developed?Yes — the README lists both latest stable and latest development releases, development is tracked on a public roadmap, and the team holds monthly community meetings. Help is available via Discord and GitHub Discussions.
