Hello @takero
have you tried the example I've mentioned? This should read and display the SigfoxID and PACNumber and if successful would tell you the hardware is ok.
Note: for M5Core2 you'll need to adapt rxPin to 13 and txPin to 14 as before.
Thanks
Felix
Hey I am thinking about buying the m5paper and I hope someone here can answer my question.
How much current does the board use in sleep?
Or maybe the more important question is the following.
If I want to develop something like a weather station. And update the display once every 10min, 30min or every hour. And between that the device is sleeping. How long could the battery last?
I don't want exact figures. What I need is some rough estimate like 1week, 1month or whatever.
Would be great if someone knows more and can help
hi @euroclie
can you please explain how did you managed to fix that problem.
i Installed this drivers also and i seems that windows can find my device, the problem is that i can't burn anything on it because it is shown as disconnected
Hi,
I get what you mean, it makes a lot of sense. The one you get is surly the soldering mistake , because they didn't put enough tin on the soldering pad. We definitely could do something to improve structures deign just like what you come up with, but its not gonna help that much if we have the bad soldering.

M5 Wheel of BALA is connected with M5Fire via pogo pin ( gpio21 gpio22 gnd 5v ).
The IIC address of M5 Wheel ( 2-DC-driver module ) is 0x56.

@b1063n said in External Power - What is possible?:
So, did anyone find a solution. I was about to buy it, but then when I look at the documentation for the power supply voltage I cannot find it! Documentation is quite poor I must add.
I do not need battery operated solution, and the USB power is super ugly and inconvenient!
I need to use external 5V power supply connected to pins inside the board in a professional manner (no pcb hacking). Is this not possible? I cannot believe it!!
Yes it is possible as the Stackable modules provide internal power to M5Stack cores. (Sorry been working on my books and documenting units with demos this weekend.)
The documents I have, show that each stackable module has its own voltage regulator that delivers 5 volts to pin 28 of the internal bus (+5V).
If you look at the Proto module you will see that these pins are marked ready for you.
