Hi team,

Thanks,

@codeblue it’s written on the round card in the packaging and on the M5Stack product web page

I haven't tried the M5dial, but If you look at the hardware documentation (diagrams) for both the
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)
-
could it be that BtnA is a virtual touchscreen button?

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

@codeblue Look on the Dials document page as there are descriptions and circuit diagrams
