"Wake" on the front of the M5dial (the "main button" of the M5Dial I suppose) connected to the power-on circuit but routed via the "wake" signal to ESP-G42. (designated "S1" on the M5dial diagram.)

thanks. I think that's it , but I just curious , how you can tell the "S4" is routed to the G42? sorry I know nothing about the hardware. lol

M5Dial and the M5StampS3 there is no mention of a BtnA.

As far as I can figure out there are 3 buttons in total:

  • "RST" on the back of the M5dial connected to ESP32-EN" (designated "S4" on the m5dial-diagram)
  • "Wake" on the front of the M5dial (the "main button" of the M5Dial I suppose) connected to the power-on circuit but routed via the "wake" signal to ESP-G42. (designated "S1" on the M5dial diagram.)
  • The "user button" of the M5StampS3 connected to ESP-G0 (designated "S1" on the M5StampS3 diagram)
