Flashing Blue LED? #16

Closed kosso closed 4 years ago

kosso commented 4 years ago

Re: TTGO T-Journal type camera board:

I see the RED LED in the schematic, which appears to show when 3v power is on. And I can see that therefore is cannot be controlled by code.

But I do not see the BLUE LED anywhere in the schematics or documentation.

Is there a way to stop this flashing? (Apart from desoldering it)

Also, does this board include a battery charging circuit via the small connector? (And is this related to the Blue LED?)

Thanks!

Aha! It's OK. I now found the correct schematic!

I see that the Blue LED is for the charging circuit which is managed by the IP5306 chip.
