I created a devise, and I also want it to be a 5v power pack…
The XIAO is powered via de 5v pin, a buck converter (2amp max) is used to regulate from 12v to 5v.
A charge balance board is used to handle the 3x18650 cells, outputting 12v.
So I tried connecting:
- Another XIAO: It successfully powers On the connected XIAO! it blinks…
- a Pixel 2XL smartphone (with 30w fast charge): it shows that it is charging for 1 sec. Then it stops charging it. I think is has to do something with the power drawn.
Any idea about what is happening? and is there a workaround? Do I have to enable something?
