Expansion board 3.1

[poesel]

How do I access the 'S1' button? I couldn't find any documentation (actually for the whole board... :( )

Thanks

According to the documentation it's P14 but doesn't seem to work.
It will be P10 but I'm already using that for I2C

@jimmo - thanks!

Sorry I saw the other comments about firmware first.

It's P10.

The documentation could be better of course but FYI you can actually see the trace on the bottom of the PCB.

Yes, my question was how to find and press the button...

Come on - with access I obviously meant 'how can I read the buttons status?'. Is it connected to an IO? Or does it have another purpose?

See this thread -- https://forum.pycom.io/topic/4684/exit-from-dfu-mode

I recommend not trying to update the firmware until there's an update from Pycom.

and have issues with the firmware update for the 3.1...

Thou shall use the firmware for the 3.1 and not the 3.0 board. That's all you can find.

What do you mean by "access"? It is right there on the board...?
But yes, I could not find any documentation either and have issues with the firmware update for the 3.1...
