Hi all,

I have tried to use the battery interface under the board.
According to the AXP209 notice,
  • Voltage range: 2.9 V - 6.3V (AMR:-0.3V-11V)


So I have plugged 5V@2A (from a power bank) and try to start.
But I have problems. My USB amperage indicator says 3,5A and 3.5V, and the board don't start. (nothing append, no red led)
After that, I returned to the classic jack alimentation and the board start normally.

What I have missed ?

Thanks

Oh I'm stupid.
Adjustable USB or AC-adapter current limit (4.4V/900mA/500mA/100mA)
XD

But can we use USB (mouse, keyboard) with a such alimentation ?
