@ajb2k3 ,
shall we continue this discussion somewhere else ? Move it to another place in the forum ?

Regarding the question ... I can't see any LEDs

@ajb2k3 ,

I think so ... the screws seems to be tightened

Hi ajb2k3,
I measured it with a multimeter ... no I didn't put the probes into the connector ... first I applied the original grove cable to the M5 and then extended it by breadboard cables, where it was easy and safe to connect the multimeter.
And so I did for all three ports ... only on port A 5V could be seen

Hi 2 All,

I'm Red_Ant from Germany.
I thought, it's time to start experimenting with these Arduino/ESP/whatever stuff, and I'm honest, I'm a real newbie. For that reason I decided to buy the M5Stack IoT StarterKit (white device).
First hurdle was the setup of the editors ... I'm running Linux Mint.
No chance to get it running ... so I switched to WIN10 ... no chance. Finally I figured out, that the short USB cable of the starter kit doesn'twork. With my Samsung phone line, everything worked fine.
Great .... but
Next I started with the sample app, already installed on the M5 ... ok, sensor on port A worked fine.
But on port B, I wasn't able to get any of the other sensors running ... no feedback signal.
I also found the explanation: no 5V on port B or C. Connecting the sensors to the 5V of port A (only 5V and GND) and all sensors worked fine.
After all this, I thought to be ready for my first program ... so I give it a trial.
What to say ... of course no success ... something with "uiflow lib missing".
I also figured out, what's the problem: very old firmware.
And after updating the firmware everything was fine ... except the missing 5V on port B & C.
Any ideas ? Is there a switch to turn it on ? Setting/parameter/ ....

Currently I've got the feeling, that I have to return the device.

(Buy the way: in parallel I started with an Arduino ... without any trouble)
