Thank you for the feedback. The M5-Atom utube tutorial breezes through the Arduino Tool tab Board Manager portion by setting it up for M5Stick-C, as there is no M5-Atom selection, but when I compile, I get “Error compiling for board M5Stick-C.” I’m using an M5-ATOM “Button” example, and my Atom is plugged into my Windows PC USB Port. Of course, I’ve added the M5-Atom library. In Arduino under File tab Preferences I’ve included Board Manager https://dl.espressif.com/dl/package_esp32_index.json. Not sure where to go from here…

In Arduino, is there an add-on (via the Board Manager) to upload to the M5 Atom?
