I have a battery-powered device with my SODAQ SARA R412M board using a Lipo battery.
There is also a switch to the battery input so as to power on/off the device.
I want to be able to recharge the battery fast when the device is powered off.
Can I add a power switch to the board instead of on the one I have for the battery input?
Can I use the onboard USB port for charging while the board is powered off or both on/off?
What is the charging rate of the USB port charging circuit?
Thank you in advance,
