Hi there,
Can I connect a 5volt 2ampere USB power supply to a Pocket Beagle? Would the excessive amount of current damage the board? Will it over-heated?
thanks
Andrea

The current flow will only be what the device is using. Power supplies
do not push /current/ beyond demand. They can push voltage (which is how
charging systems work -- by pushing a higher voltage than the destination
device and monitoring the current flow [and temperature -- modern batteries
have complex charging criteria] for a fall off as the battery peaks out).
