this shield claims to have a 3V logic level pin
Me No Dev
@me-no-dev
so they have a convertor there to be able to work on 5V
Stavros Korokithakis
@skorokithakis
so that should work, at least
right
looks like an FTDI cable will work as well

@mrbig @me-no-dev The official one I thought should be ARDUINO_ARCH_ESP8266 and not ESP8266.

apprently the quality of the stabilisation on those cheap ones leaves a lot to be desired, etc
john lee from expressif told us once that they have an idea and will come up with some sort of mains power solution

But that is true for almost any thing from China : a year ago, I've received Wall-PSUs with barrel, one of them had a solder blob inside touching the AC, when I've plug it, 120VAC across OlimexBoard and USB hub, both gave smoke. Fortunately, my PC itself been undamaged, protected by this USB Hub.

@tzapu
ffs
glad your pc is ok
that was the mention

@martinayotte
Yes ! now, I'm testing any unit that is connected to AC to make sure there is no AC on the DC side.
Stavros Korokithakis

Is there something to generate a stable 32k frequenz? ticker-lib does not give more than ms... and digging in the source lead to not much... any idea?

Hi, I'm trying to use WiFi.disconnect() to clear previously stored WiFi connection parameters, but the ESP crashes when I call this method, any idea why this happens?

Regarding the WiFi.disconnect() crash, when I call this method, this is the crash log I'm seeing:
