ESP32 Battery powered boards - How to stop them powering up by plugging in usb.

Postby Fugazi » Fri Apr 20, 2018 10:03 am

Hi

I have a few TTGO boards with a switch on them and the battery charge.

It seems however that if you plug in USB , the esp32 comes in regardless of the switch position, so to charge the battery the esp32 has to be on.

To me this seems pointless and a bad design, who wants the board to come on when you plug usb in ? if you want it on, you can just switch it on ?!

Anyone any ideas how to sort this problem out, i cant find anyway of stopping the usb turning the esp32 on.

Its a major issue for my project and I would guess quite a few peoples!

Thanks

Phil
