PaHub With M5Stick
No, not directly. The StickC can not directly provide enough power for it to work but there is away around.
As to my post about Pahub access cracked. That was written before we had the functions added in UIFlow.
It feels like the documentation is badly broken. I have experienced this firsthand that it is almost impossible to decide what to buy just by looking at the parts themselves.
I have created and cancelled two orders already after going through tens of forum posts and then realizing that the parts are incompatible.
To add to the confusion, some core modules like the M5Go Lite Kit and M5go Starter kit has same "Included Parts" sections, but are different in price. See the two included screenshots. The title of the tab will tell you exactly which product the screenshot is for. The left image is of IoT Starter Kit, the right one is M5G0 Lite. Ofcourse both of them have six Units as written, but the photos show a different story.
Things like these are all around the site.
If I have a 1 to 3 Hub along with the following devices
a) A PBHub to connect (Non I2C) digital and analog sensors
b) An ENV Unit
c) A RFID Unit.
Will the 1 to 3 hub be able to connect to all the three (a,b, and c) using an M5StickC, without needing a PAHub.
@rupin-chheda Unfortunately it will not work.
Technically it should work as they all have different I2C address' but again the same power limitations may apply
@ajb2k3 thanks for your response. If I replace the M5stickc with a Basic Dev Kit, will I still have these problems, with the same combination of units?
@rupin-chheda no, if you replace the stick with a stack then it should be ok.
@rupin-chheda I’m not sure what’s happening here as I checked the listings and they are both different. The lite only shows the env sensor included.
@ajb2k3 Can you suggest how much current can the I2C Grove port can source? Is this documented somewhere?
@ajb2k3 I reported this to Mindy and Allen, seems they have updated this.
@rupin-chheda as far as I know it is not documented how much current it can source, all I can say that I have tried various things and keep getting “device not connected “ when it is connected. This is a sign that the device isn’t getting enough power.
