Hi,
I use ESP32-H2 SuperMini boards. Thanks to @PrairieSnpr the software part is looking very good !!
My question is :
When the board is powered via USB cable or 5v (thru the 5v pin), the “Bat” led is blinking nonstop.
When the board is powered via 3,3v (thru the 3,3v pin), the “Bat” led is fine. Nothing to report.
How could I make it work with 5v power supply ?
The whole system will be powered with 5v around the house and I would like the boards NOT to blink.
Have a good day 
I think this is just a bug with the super minis, my esp32-c6 super minis do the same thing, the higher end dev kits don’t. Some people say you can connect a 10uf capacitor between the battery and ground pins, but the super minis I have don’t have a battery pin or a charge controller. Honestly, just pulling the battery led off the pcb is probably the fastest solution.
Oh !
That is a bit drastic, isn’t it ? 
There is no software control over that part ?
At this point, I would rather install a voltage regulator between the power supply and the boards. They will all be on the same isolated circuit.
One board drains 31mA under 3,3V.
I will have around 25 of them. It should be around 775mA for the complete house (plus the cabling resistance).
We should be good.
I will keep a spare voltage regulator for the time that one will eventually die.
Any educated comment on that idea ?
Thanks
I think you will like that option better. The super mini on board regulator isn’t effecient, so you would be adding a better regulator. This would also allow you to bump the suoply voltage up, I don’t know what your distances are, but 12 or 24 volts powering the boards will have less voltage drop and be easier to work with.
You think of a voltage regulator per board ?
I was thinking of a “big” one in front of the whole circuit but it may not be the best option (but the easiest)… I don’t know if I have room for a voltage regulator in each box
