Hello! I am wondering when and how the HPWR pins available on M5STack Core bus are used. I have checked and the Pins are floating on the COre and are not connected in most of the stackable module. As I am having some issues with Battery pin and +5V pin between the core and the Shield (false contacts), I have used these pins to "reinforce" the 5V or the Battery, depending on my needs.
It would be also interesting to undertsand why just one pin has been given to the Battery and to the +5V. As an improvement, I think the HPWR pins should be used to strengthen the Battery ore the +5V PINS.
