- ESP32-C3-WROOM-02 は非常に熱に弱いモジュールです。ボード裏面にはサーマルパッドをはんだづけするための穴が空いていますが、熱を与えすぎに注意してください。BOOTH のキットでは熱伝導テープを添付しています。カットして、モジュールに貼り付けて、青いテープ、透明テープを剥がして利用ください。モジュールが浮きすぎないように押さえつけて利用ください。

Questions
What parts does the ESP32-H2-MINI-1 use?
46 parts, built around the AMS1117, ESP32-H2-MINI-1U and PMEG2010ER,115-JSM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32-H2-MINI-1 KiCad files?
From the 74th/esp32-dev-boards repository on GitHub, at the commit this page was made from: the board is ESP32-H2-MINI-1/with-lipo/ESP32-H2-MINI-1.kicad_pcb and its schematic ESP32-C3-MINI-1/ESP32-C3-MINI-1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-H2-MINI-1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
